NEAT: the calories you burn without calling it exercise
Fidgeting, standing, pacing, carrying things upstairs. It adds up to more than your gym sessions, and it drops without you noticing the moment you start dieting.
Weight and mental health: the loop that runs both ways
Depression makes weight gain more likely. Weight gain makes depression more likely. Neither fact tells you which one started it, and that matters more than it sounds.
Hair supplements: what the evidence says, including the harms
The most useful thing to know about hair supplements is not whether they grow hair. It is that a few of them can make you shed, and one can wreck your blood tests.
Hair loss in your 20s: why it hits harder and why timing matters

Nearly every man’s hairline moves back a bit in his twenties. Telling that apart from the start of something else takes a magnifier and, usually, six months.
Scarring alopecia: the hair loss that needs seeing this week
Most hair loss can wait for an appointment. This is the category that cannot, because what is lost while you wait does not come back.

Microneedling for hair loss: a large effect on hair count, and no standard protocol
More hairs, but not demonstrably thicker ones, from trials that each did it slightly differently. Useful, genuinely — as long as you know what it is adding to.
