How light can shift your mood and mental health

This is the next article in our ‘Light and health’ series, where we look at how light affects our physical and mental health in sometimes surprising ways. Read other articles in the series.

It’s spring and you’ve probably noticed a change in when the Sun rises and sets. But have you also noticed a change in your mood?

We’ve known for a while that light plays a role in our wellbeing. Many of us tend to feel more positive when spring returns.

But for others, big changes in light, such as at the start of spring, can be tough. And for many, bright light at night can be a problem. Here’s what’s going on.

An ancient rhythm of light and mood

In an earlier article in our series, we learned that light shining on the back of the eye sends “timing signals” to the brain and the master clock of the circadian system. This clock coordinates our daily (circadian) rhythms.

“Clock genes” also regulate circadian rhythms. These genes control the timing of when many other genes turn on and off during the 24-hour, light-dark cycle.

But how is this all linked with our mood and mental health?

Circadian rhythms can be disrupted. This can happen if there are problems with how the body clock develops or functions, or if someone is routinely exposed to bright light at night.

When circadian disruption happens, it increases the risk of certain mental disorders. These include bipolar disorder and atypical depression (a type of depression when someone is extra sleepy and has problems with their energy and metabolism).

Light on the brain

Light may also affect circuits in the brain that control mood, as animal studies show.

There’s evidence this happens in humans. A brain-imaging study showed exposure to bright light in the daytime while inside the scanner changed the activity of a brain region involved in mood and alertness.

Another brain-imaging study found a link between daily exposure to sunlight and how the neurotransmitter (or chemical messenger) serotonin binds to receptors in the brain. We see alterations in serotonin binding in several mental disorders, including depression.

What happens when the seasons change?

Light can also affect mood and mental health as the seasons change. During autumn and winter, symptoms such as low mood and fatigue can develop. But often, once spring and summer come round, these symptoms go away. This is called “seasonality” or, when severe, “seasonal affective disorder”.

What is less well known is that for other people, the change to spring and summer (when there is more light) can also come with a change in mood and mental health. Some people experience increases in energy and the drive to be active. This is positive for some but can be seriously destabilising for others. This too is an example of seasonality.

Most people aren’t very seasonal. But for those who are, seasonality has a genetic component. Relatives of people with seasonal affective disorder are more likely to also experience seasonality.

Seasonality is also more common in conditions such as bipolar disorder. For many people with such conditions, the shift into shorter day-lengths during winter can trigger a depressive episode.

Counterintuitively, the longer day-lengths in spring and summer can also destabilise people with bipolar disorder into an “activated” state where energy and activity are in overdrive, and symptoms are harder to manage. So, seasonality can be serious.

Alexis Hutcheon, who experiences seasonality and helped write this article, told us:

[…] the season change is like preparing for battle – I never know what’s coming, and I rarely come out unscathed. I’ve experienced both hypomanic and depressive episodes triggered by the season change, but regardless of whether I’m on the ‘up’ or the ‘down’, the one constant is that I can’t sleep. To manage, I try to stick to a strict routine, tweak medication, maximise my exposure to light, and always stay tuned in to those subtle shifts in mood. It’s a time of heightened awareness and trying to stay one step ahead.

So what’s going on in the brain?

One explanation for what’s going on in the brain when mental health fluctuates with the change in seasons relates to the neurotransmitters serotonin and dopamine.

Serotonin helps regulate mood and is the target of many antidepressants. There is some evidence of seasonal changes in serotonin levels, potentially being lower in winter.

Dopamine is a neurotransmitter involved in reward, motivation and movement, and is also a target of some antidepressants. Levels of dopamine may also change with the seasons.

But the neuroscience of seasonality is a developing area and more research is needed to know what’s going on in the brain.

How about bright light at night?

We know exposure to bright light at night (for instance, if someone is up all night) can disturb someone’s circadian rhythms.

This type of circadian rhythm disturbance is associated with higher rates of symptoms including self-harm, depressive and anxiety symptoms, and lower wellbeing. It is also associated with higher rates of mental disorders, such as major depression, bipolar disorder, psychotic disorders and post-traumatic stress disorder (or PTSD).

Why is this? Bright light at night confuses and destabilises the body clock. It disrupts the rhythmic regulation of mood, cognition, appetite, metabolism and many other mental processes.

But people differ hugely in their sensitivity to light. While still a hypothesis, people who are most sensitive to light may be the most vulnerable to body clock disturbances caused by bright light at night, which then leads to a higher risk of mental health problems.

Where to from here?

Learning about light will help people better manage their mental health conditions.

By encouraging people to better align their lives to the light-dark cycle (to stabilise their body clock) we may also help prevent conditions such as depression and bipolar disorder emerging in the first place.

Healthy light behaviours – avoiding light at night and seeking light during the day – are good for everyone. But they might be especially helpful for people at risk of mental health problems. These include people with a family history of mental health problems or people who are night owls (late sleepers and late risers), who are more at risk of body clock disturbances.

  • Stickers and wristbands aren’t a reliable way to prevent mosquito bites. Here’s why

    10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.

    Protecting yourself and family from mosquito bites can be challenging, especially in this hot and humid weather. Protests from young children and fears about topical insect repellents drive some to try alternatives such as wristbands, patches and stickers.

    These products are sold online as well as in supermarkets, pharmacies and camping stores. They’re often marketed as providing “natural” protection from mosquitoes.

    But unfortunately, they aren’t a reliable way to prevent mosquito bites. Here’s why – and what you can try instead.

    Why is preventing mosquito bites important?

    Mosquitoes can spread pathogens that make us sick. Japanese encephalitis and Murray Valley encephalitis viruses can have potentially fatal outcomes. While Ross River virus won’t kill you, it can cause potentially debilitating illnesses.

    Health authorities recommend preventing mosquito bites by: avoiding areas and times of the day when mosquitoes are most active; covering up with long sleeved shirts, long pants, and covered shoes; and applying a topical insect repellent (a cream, lotion, or spray).

    I don’t want to put sticky and smelly repellents on my skin!

    While for many people, the “sting” of a biting mosquitoes is enough to prompt a dose of repellent, others are reluctant. Some are deterred by the unpleasant feel or smell of insect repellents. Others believe topical repellents contain chemicals that are dangerous to our health.

    However, many studies have shown that, when used as recommended, these products are safe to use. All products marketed as mosquito repellents in Australia must be registered by the Australian Pesticides and Veterinary Medicines Authority; a process that provides recommendations for safe use.

    How do topical repellents work?

    While there remains some uncertainty about how the chemicals in topical insect repellents actually work, they appear to either block the sensory organs of mosquitoes that drive them to bite, or overpower the smells of our skin that helps mosquitoes find us.

    Diethytolumide (DEET) is a widely recommended ingredient in topical repellents. Picaridin and oil of lemon eucalyptus are also used and have been shown to be effective and safe.

    How do other products work?

    “Physical” insect-repelling products, such as wristbands, coils and candles, often contain a botanically derived chemical and are often marketed as being an alternative to DEET.

    However, studies have shown that devices such as candles containing citronella oil provide lower mosquito-bite prevention than topical repellents.

    A laboratory study in 2011 found wristbands infused with peppermint oil failed to provide full protection from mosquito bites.

    Even as topical repellent formulations applied to the skin, these botanically derived products have lower mosquito bite protection than recommended products such as those containing DEET, picaridin and oil of lemon eucalyptus.

    Wristbands infused with DEET have shown mixed results but may provide some bite protection or bite reduction. DEET-based wristbands or patches are not currently available in Australia.

    There is also a range of mosquito repellent coils, sticks, and other devices that release insecticides (for example, pyrethroids). These chemicals are primarily designed to kill or “knock down” mosquitoes rather than to simply keep them from biting us.

    What about stickers and patches?

    Although insect repellent patches and stickers have been available for many years, there has been a sudden surge in their marketing through social media. But there are very few scientific studies testing their efficacy.

    Our current understanding of the way insect repellents work would suggest these small stickers and patches offer little protection from mosquito bites.

    At best, they may reduce some bites in the way mosquito coils containing botanical products work. However, the passive release of chemicals from the patches and stickers is likely to be substantially lower than those from mosquito coils and other devices actively releasing chemicals.

    One study in 2013 found a sticker infused with oil of lemon eucalyptus “did not provide significant protection to volunteers”.

    Clothing impregnated with insecticides, such as permethrin, will assist in reducing mosquito bites but topical insect repellents are still recommended for exposed areas of skin.

    Take care when using these products

    The idea you can apply a sticker or patch to your clothing to protect you from mosquito bites may sound appealing, but these devices provide a false sense of security. There is no evidence they are an equally effective alternative to the topical repellents recommended by health authorities around the world. It only takes one bite from a mosquito to transmit the pathogens that result in serious disease.

    It is also worth noting that there are some health warnings and recommendations for their use required by Australian Pesticides and Veterinary Medicines Authority. Some of these products warn against application to the skin (recommending application to clothing only) and to keep products “out of reach of children”. This is a challenge if attached to young children’s clothing.

    Similar warnings are associated with most other topical and non-topical mosquito repellents. Always check the labels of these products for safe use recommendations.

    Are there any other practical alternatives?

    Topical insect repellents are safe and effective. Most can be used on children from 12 months of age and pose no health risks. Make sure you apply the repellent as a thin even coat on all exposed areas of skin.

    But you don’t need “tropical strength” repellents for short periods of time outdoors; a range of formulations with lower concentrations of repellent will work well for shorter trips outdoors. There are some repellents that don’t smell as strong (for example, children’s formulations, odourless formulations) or formulations that may be more pleasant to use (for example, pump pack sprays).

    Finally, you can always cover up. Loose-fitting long-sleeved shirts, long pants, and covered shoes will provide a physical barrier between you and mosquitoes on the hunt for your or your family’s blood this summer.The Conversation

  • Simply The Pits: These Underarm Myths!

    10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.

    Are We Taking A Risk To Smell Fresh As A Daisy?

    Yesterday, we asked you for your health-related view of underarm deodorants.

    So, what does the science say?

    They can cause (or increase risk of) cancer: True or False?

    False, so far as we know. Obviously it’s very hard to prove a negative, but there is no credible evidence that deodorants cause cancer.

    The belief that they do comes from old in vitro studies applying the deodorant directly to the cells in question, like this one with canine kidney tissues in petri dishes:

    Antiperspirant Induced DNA Damage in Canine Cells by Comet Assay

    Which means that if you’re not a dog and/or if you don’t spray it directly onto your internal organs, this study’s data doesn’t apply to you.

    In contrast, more modern systematic safety reviews have found…

    ❝Neither is there clear evidence to show use of aluminum-containing underarm antiperspirants or cosmetics increases the risk of Alzheimer’s Disease or breast cancer.

    Metallic aluminum, its oxides, and common aluminum salts have not been shown to be either genotoxic or carcinogenic.

    Source: Systematic review of potential health risks posed by pharmaceutical, occupational and consumer exposures to metallic and nanoscale aluminum, aluminum oxides, aluminum hydroxide and its soluble salts

    (however, one safety risk it did find is that we should avoid eating it excessively while pregnant or breastfeeding)

    Alternatives like deodorant rocks have fewer chemicals and thus are safer: True or False?

    True and False, respectively. That is, they do have fewer chemicals, but cannot in scientific terms be qualifiably, let alone quantifiably, described as safer than a product that was already found to be safe.

    Deodorant rocks are usually alum crystals, by the way; that is to say, aluminum salts of various kinds. So if it was aluminum you were hoping to avoid, it’s still there.

    However, if you’re trying to cut down on extra chemicals, then yes, you will get very few in deodorant rocks, compared to the very many in spray-on or roll-on deodorants!

    Soap and water is a safe, simple, and sufficient alternative: True or False?

    True or False, depending on what you want as a result!

    • If you care that your deodorant also functions as an antiperspirant, then no, soap and water will certainly not have an antiperspirant effect.
    • If you care only about washing off bacteria and eliminating odor for the next little while, then yes, soap and water will work just fine.

    Bonus myths:

    There is no difference between men’s and women’s deodorants, apart from the marketing: True or False?

    False! While to judge by the marketing, the only difference is that one smells of “evening lily” and the other smells of “chainsaw barbecue” or something, the real difference is…

    • The “men’s” kind is designed to get past armpit hair and reach the skin without clogging the hair up.
    • The “women’s” kind is designed to apply a light coating to the skin that helps avoid chafing and irritation.

    In other words… If you are a woman with armpit hair or a man without, you might want to ignore the marketing and choose according to your grooming preferences.

    Hopefully you can still find a fragrance that suits!

    Shaving (or otherwise depilating) armpits is better for hygiene: True or False?

    True or False, depending on what you consider “hygiene”.

    Consistent with popular belief, shaving means there is less surface area for bacteria to live. And empirically speaking, that means a reduction in body odor:

    A comparative clinical study of different hair removal procedures and their impact on axillary odor reduction in men

    However, shaving typically causes microabrasions, and while there’s no longer hair for the bacteria to enjoy, they now have access to the inside of your skin, something they didn’t have before. This can cause much more unpleasant problems in the long-run, for example:

    ❝Hidradenitis suppurativa is a chronic and debilitating skin disease, whose lesions can range from inflammatory nodules to abscesses and fistulas in the armpits, groin, perineum, inframammary region❞

    Read more: Hidradenitis suppurativa: Basic considerations for its approach: A narrative review

    And more: Hidradenitis suppurativa: Epidemiology, clinical presentation, and pathogenesis

    If this seems a bit “damned if you do; damned if you don’t”, this writer’s preferred way of dodging both is to use electric clippers (the buzzy kind, as used for cutting short hair) to trim hers down low, and thus leave just a little soft fuzz.

    What you do with yours is obviously up to you; our job here is just to give the information for everyone to make informed decisions whatever you choose 🙂

    Take care!

  • Why do I poo in the morning? A gut expert explains

    10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.

    No, you’re not imagining it. People really are more likely to poo in the morning, shortly after breakfast. Researchers have actually studied this.

    But why mornings? What if you tend to poo later in the day? And is it worth training yourself to be a morning pooper?

    To understand what makes us poo when we do, we need to consider a range of factors including our body clock, gut muscles and what we have for breakfast.

    Here’s what the science says.

    H_Ko/Shutterstock

    So morning poos are real?

    In a UK study from the early 1990s, researchers asked nearly 2,000 men and women in Bristol about their bowel habits.

    The most common time to poo was in the early morning. The peak time was 7-8am for men and about an hour later for women. The researchers speculated that the earlier time for men was because they woke up earlier for work.

    About a decade later, a Chinese study found a similar pattern. Some 77% of the almost 2,500 participants said they did a poo in the morning.

    But why the morning?

    There are a few reasons. The first involves our circadian rhythm – our 24-hour internal clock that helps regulate bodily processes, such as digestion.

    For healthy people, our internal clock means the muscular contractions in our colon follow a distinct rhythm.

    There’s minimal activity in the night. The deeper and more restful our sleep, the fewer of these muscle contractions we have. It’s one reason why we don’t tend to poo in our sleep.

    But there’s increasing activity during the day. Contractions in our colon are most active in the morning after waking up and after any meal.

    One particular type of colon contraction partly controlled by our internal clock are known as “mass movements”. These are powerful contractions that push poo down to the rectum to prepare for the poo to be expelled from the body, but don’t always result in a bowel movement. In healthy people, these contractions occur a few times a day. They are more frequent in the morning than in the evening, and after meals.

    Breakfast is also a trigger for us to poo. When we eat and drink our stomach stretches, which triggers the “gastrocolic reflex”. This reflex stimulates the colon to forcefully contract and can lead you to push existing poo in the colon out of the body. We know the gastrocolic reflex is strongest in the morning. So that explains why breakfast can be such a powerful trigger for a bowel motion.

    Then there’s our morning coffee. This is a very powerful stimulant of contractions in the sigmoid colon (the last part of the colon before the rectum) and of the rectum itself. This leads to a bowel motion.

    How important are morning poos?

    Large international surveys show the vast majority of people will poo between three times a day and three times a week.

    This still leaves a lot of people who don’t have regular bowel habits, are regular but poo at different frequencies, or who don’t always poo in the morning.

    So if you’re healthy, it’s much more important that your bowel habits are comfortable and regular for you. Bowel motions do not have to occur once a day in the morning.

    Morning poos are also not a good thing for everyone. Some people with irritable bowel syndrome feel the urgent need to poo in the morning – often several times after getting up, during and after breakfast. This can be quite distressing. It appears this early-morning rush to poo is due to overstimulation of colon contractions in the morning.

    Can you train yourself to be regular?

    Yes, for example, to help treat constipation using the gastrocolic reflex. Children and elderly people with constipation can use the toilet immediately after eating breakfast to relieve symptoms. And for adults with constipation, drinking coffee regularly can help stimulate the gut, particularly in the morning.

    A disturbed circadian rhythm can also lead to irregular bowel motions and people more likely to poo in the evenings. So better sleep habits can not only help people get a better night’s sleep, it can help them get into a more regular bowel routine.

    Regular physical activity and avoiding sitting down a lot are also important in stimulating bowel movements, particularly in people with constipation.

    We know stress can contribute to irregular bowel habits. So minimising stress and focusing on relaxation can help bowel habits become more regular.

    Fibre from fruits and vegetables also helps make bowel motions more regular.

    Finally, ensuring adequate hydration helps minimise the chance of developing constipation, and helps make bowel motions more regular.

    Monitoring your bowel habits

    Most of us consider pooing in the morning to be regular. But there’s a wide variation in normal so don’t be concerned if your poos don’t follow this pattern. It’s more important your poos are comfortable and regular for you.

    If there’s a major change in the regularity of your bowel habits that’s concerning you, see your GP. The reason might be as simple as a change in diet or starting a new medication.

    But sometimes this can signify an important change in the health of your gut. So your GP may need to arrange further investigations, which could include blood tests or imaging.

  • What Are The “Bright Lines” Of Bright Line Eating?

    10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.

    This is Dr. Susan Thompson. She’s a cognitive neuroscientist who has turned her hand to helping people to lose weight and maintain it at a lower level, using psychology to combat overeating. She is the founder of “Bright Line Eating”.

    We’ll say up front: it’s not without some controversy, and we’ll address that as we go, but we do believe the ideas are worth examining, and then we can apply them or not as befits our personal lives.

    What does she want us to know?

    Bright Line Eating’s general goal

    Dr. Thompson’s mission statement is to help people be “happy, thin, and free”.

    You will note that this presupposes thinness as desirable, and presumes it to be healthy, which frankly, it’s not for everyone. Indeed, for people over a certain age, having a BMI that’s slightly into the “overweight” category is a protective factor against mortality (which is partly a flaw of the BMI system, but is an interesting observation nonetheless):

    When BMI Doesn’t Quite Measure Up

    Nevertheless, Dr. Thompson makes the case for the three items (happy, thin, free) coming together, which means that any miserable or unhealthy thinness is not what the approach is valuing, since it is important for “thin” to be bookended by “happy” and “free”.

    What are these “bright lines”?

    Bright Line Eating comes with 4 rules:

    1. No flour (no, not even wholegrain flour; enjoy whole grains themselves yes, but flour, no)
    2. No sugar (and as a tag-along to this, no alcohol) (sugars naturally found in whole foods, e.g. the sugar in an apple if eating an apple, is ok, but other kinds are not, e.g. foods with apple juice concentrate as a sweetener; no “natural raw cane sugar” etc is not allowed either; despite the name, it certainly doesn’t grow on the plant like that)
    3. No snacking, just three meals per day(not even eating the ingredients while cooking—which also means no taste-testing while cooking)
    4. Weigh all your food (have fun in restaurants—but more seriously, the idea here is to plan each day’s 3 meals to deliver a healthy macronutrient balance and a capped calorie total).

    You may be thinking: “that sounds dismal, and not at all bright and cheerful, and certainly not happy and free”

    The name comes from the idea that these rules are lines that one does not cross. They are “bright” lines because they should be observed with a bright and cheery demeanour, for they are the rules that, Dr. Thompson says, will make you “happy, thin, and free”.

    You will note that this is completely in opposition to the expert opinion we hosted last week:

    What Flexible Dieting Really Means

    Dr. Thompson’s position on “freedom” is that Bright Line Eating is “very structured and takes a liberating stand against moderation”

    Which may sound a bit of an oxymoron—is she really saying that we are going to be made free from freedom?

    But there is some logic to it, and it’s about the freedom from having to make many food-related decisions at times when we’re likely to make bad ones:

    Where does the psychology come in?

    Dr. Thompson’s position is that willpower is a finite, expendable resource, and therefore we should use it judiciously.

    So, much like Steve Jobs famously wore the same clothes every day because he had enough decisions to make later in the day that he didn’t want unnecessary extra decisions to make… Bright Line Eating proposes that we make certain clear decisions up front about our eating, so then we don’t have to make so many decisions (and potentially the wrong decisions) later when hungry.

    You may be wondering: ”doesn’t sticking to what we decided still require willpower?”

    And… Potentially. But the key here is shutting down self-negotiation.

    Without clear lines drawn in advance, one must decide, “shall I have this cake or not?”, perhaps reflecting on the pros and cons, the context of the situation, the kind of day we’re having, how hungry we are, what else there is available to eat, what else we have eaten already, etc etc.

    In short, there are lots of opportunities to rationalize the decision to eat the cake.

    With clear lines drawn in advance, one must decide, “shall I have this cake or not?” and the answer is “no”.

    So while sticking to that pre-decided “no” still may require some willpower, it no longer comes with a slew of tempting opportunities to rationalize a “yes”.

    Which means a much greater success rate, both in adherence and outcomes. Here’s an 8-week interventional study and 2-year follow-up:

    Bright Line Eating | Research Publications

    Counterpoint: pick your own “bright lines”

    Dr. Thompson is very keen on her 4 rules that have worked for her and many people, but she recognizes that they may not be a perfect fit for everyone.

    So, it is possible to pick and choose our own “bright lines”; it is after all a dietary approach, not a religion. Here’s her response to someone who adopted the first 3 rules, but not the 4th:

    Bright Lines as Guidelines for Weight Loss

    The most important thing for Bright Line Eating, therefore, is perhaps the action of making clear decisions in advance and sticking to them, rather than seat-of-the-pantsing our diet, and with it, our health.

    We’re glad you’re enjoying them! There are a couple of reasons why we don’t, but the reasons can be aggregated into one (admittedly rare) concept: honesty

    To even try to give you these figures, we’d first need to use the metric system (or at least, a strictly mass-based system) which would likely not go well with our largely American readership, because “half a bulb of garlic, or more if you like”, and “1 cucumber” or “1 cup chopped carrot” could easily way half or twice as much, depending on the sizes of the vegetables or the chopping involved, and in the case of chopped vegetables measured by the cup, even the shape of the cup (because of geometry and the spaces left; it’s like Tetris in there). We can say “4 cups low-sodium broth” but we can’t say how much sodium is in your broth. And so on.

    And that’s without getting into the flexibility we offer with substitutions, often at a rate of several per recipe.

    We’d also need to strictly regulate your portion sizes for you, because we (with few exceptions, such as when they are a given number of burger patties, or a dessert-in-a-glass, etc) give you a recipe for a meal and leave it to you how you divide it and whether there’s leftovers.

    Same goes for things like “Extra virgin olive oil for frying”; a recipe could say to use “2 tbsp” but let’s face it, you’re going to use what you need to use, and that’s going to change based on the size of your pan, how quickly it’s absorbed into the specific ingredients that you got, which will change depending on how fresh they are, and things like that.

    By the time we’ve factored in your different kitchen equipment, how big your vegetables are, the many factors effecting how much oil you need, substitutions per recipe per making something dairy-free, or gluten-free, or nut-free, etc, how big your portion size is (we all know that “serves 4” is meaningless in reality)… Even an estimated average would be wildly misleading.

    So, in a sea of recipes saying “500 kcal per serving” from the same authors who say you can caramelize onions in 4–5 minutes “or until caramelized” and then use the 4–5 minutes figure for calculating the overall recipe time… We prefer to stay honest.

    PS: for any wondering, caramelizing onions takes closer to 45 minutes than 4–5 minutes, and again will depend on many factors, including the onions, how finely you chopped them, the size and surface of your pan, the fat you’re using, whether you add sugar, what kind, how much you stir them, the mood of your hob, and the phase of the moon. Under very favorable circumstances, it could conceivably be rushed in 20 minutes or so, but it could also take 60. Slow-cooking them (i.e. in a crock pot) over 3–4 hours is a surprisingly viable “cheat” option, by the way. It’ll take longer, obviously, but provided you plan in advance, they’ll be ready when you need them, and perfectly done (the same claim cannot be made if you budgeted 4–5 minutes because you trusted a wicked and deceitful author who wants to poop your party).

    Take care!
