I'm 36. I'm a physician. I take a statin—and ezetimibe—every day. No symptoms. No cardiac history. Just an honest read of the evidence. Here's what I found—and why I stopped waiting for a reason to act.

Eating the same meals on repeat was associated with 40% greater weight loss.

Some doctors say wearables & epigenetic age tests aren’t useful because they aren’t clinically approved But a new study of 178 people over a year says otherwise When people saw their data & biological age, they changed behavior & saw measurable improvements in health

Zinc is required for testosterone synthesis in Leydig cells. It's a cofactor for the steroidogenic enzymes that convert cholesterol to testosterone, and it protects Leydig cells from oxidative damage. When zinc is deficient, testosterone production drops. When zinc is restored, testosterone recovers. The landmark study is Prasad et al. (1996), which demonstrated this in two separate arms. In four young men, restricting dietary zinc for 20 weeks dropped serum testosterone from 39.9 to 10.6 nmol/L, a 73% decline. In a separate group of nine elderly men who were marginally zinc-deficient at baseline, supplementing with zinc gluconate for 3-6 months raised testosterone from 8.3 to 16.0 nmol/L. Two different populations, same conclusion: zinc status and testosterone are tightly linked. Here's where the supplement industry misrepresents the data. Every testosterone booster on the market contains zinc. But the only independent study testing ZMA (zinc + magnesium aspartate) in men who already consumed adequate zinc found zero effect on total or free testosterone (Koehler et al., 2009). The only positive ZMA study (Brilla 2000) was funded by the manufacturer and co-authored by the patent holder. The effect of zinc on testosterone is permissive, not stimulatory. If you're deficient, correcting the deficiency restores normal production. If you're sufficient, adding more does nothing. The RDA for adult males is 11 mg/day. Most men eating a mixed diet meet this without supplementation. Before buying a zinc-based testosterone product, check your status first. The expensive part isn't the zinc. It's knowing whether you actually need it. Sources: Prasad et al., Nutrition, 1996. Koehler et al., Eur J Clin Nutr, 2009. Brilla & Conte, JEPonline, 2000.

93 years & 231 days old Ann Esselstyn dead hangs for 2 min 52 seconds! To set new WR. (Maybe we call it live hangs instead now?) Distal strength reflects many things.
