Will Harlow, the over-50s physio, shows us how to train now to stay safe later: Don’t be without a leg to stand on Unless of course you don’t have legs, in which case this video isn’t as helpful for you, and we recommend triceps dips instead (explosive push upwards, controlled lowering back down), which will…

There are two side to the story: 🎵 If you have half a brain 🎵 Many birds and mammals (humans included) can sleep with one brain hemisphere in deeper sleep while the other remains in lighter sleep and more active, allowing them to stay partially alert to their surroundings. This is called asymmetrical sleep. In…

Dr. Amy Konvalin explains: Stretching a nerve rarely helps …because nerves are not particularly stretchy! Which means that stretching the sciatic nerve can aggravate an already irritated nerve because irritated nerves generally don’t respond well to being stretched. There can be some temporary relief, because stretching can initially make sciatic pain feel better briefly because…

Social connection is important for all of us at any age, but if all our friends are of our own generation, that’s likely to become limiting: Friends through the ages “How can people at different life stages possibly relate to each other?”, many ask. And the answer is: by actually letting down the barriers and…

Dr. Alyssa Kuhn, the arthritis specialist physio, shows us what we can do: The movements that work for you Squats and lunges are very valuable for building and maintaining mobility (flexibility and strength) in ways that are important, and knee pain with traditional versions doesn’t mean you need to stop strengthening your legs.

Dr. Andrea Suarez, dermatologist, gives us her professional insights: The selling point First of all, what it actually is: PDRN stands for polydeoxyribonucleotide and refers to a mixture of DNA fragments, commonly listed in skincare as sodium DNA.

Menopause can exacerbate this because alcohol can…

It’s mostly not about your age: The doorway effect Forgetting why you went into a room is mostly not about your age at all, and is rather about the doorway effect, whereby entering a new room can make you temporarily forget what you intended to do because the brain treats the change in location as…

Will Harlow, the over-50s specialist physio, shows us how: Reaching for good health The rotator cuff is a collection of four small, deep shoulder muscles that stabilize your shoulder joint and keep your arm securely in its socket during movement. Unlike larger muscles, their primary role is stability rather than producing power. However, that also…

Dr. Mia Nacamulli gives us some food for thought: You are what you eat Aside from water, most of the brain’s weight comes from fats, with proteins, amino acids, micronutrients, and glucose making up much of the rest. These nutrients influence brain function, development, mood, and energy. Although the brain accounts for only about 2%…

Dr. Alyssa Kuhn, arthritis expert, keeps us on our toes: Three ways to do it Walking is great, but it is by its very nature repetitive, and that means it doesn’t exactly improve mobility (though it does help maintain it, within a small range), and nor does it really improve strength (though it does help…

Dr. Amy Konvalin, physical therapist, gives her insights: It’s not about your knee Or at least, it’s often not.
