The GLP-1 muscle loss panic scared me into training at 50. It turned out overblown, but the habit stuck. What the evidence actually says about muscle, and why you train after 50.
A million-person Lancet study shows older adults with obesity now match normal-weight peers on blood pressure and cholesterol, thanks to cheap statins and blood-pressure pills, not weight loss.
The “five times the risk” number is real. The useful lesson for a fifty-year-old is smaller, less sexy, and more actionable. I have read the claim that VO2 max is the single best predictor of how long you will live so many times that I had stopped seeing it. It is everywhere in the longevity
Equinox sells a $40,000 longevity membership with a thousand people waiting. I run the same core protocol out of my garage for a few thousand a year. Here’s where the other $39,000 actually goes, and why some of the most expensive testing can leave you worse off.

Most “AI predicts disease” papers don’t survive a second read. This one does, and it points at a kind of heart risk your echo was never built to see. I’ve spent my whole career in machine learning, so I read the steady drip of “AI predicts your death” headlines the way a mechanic reads ads
I take two drugs that would get an Olympian banned: testosterone and a GLP-1. I will never compete, so the only thing they enhance is my ability to climb stairs and lift a barbell after 50. Here is what they actually do, and what they don’t.
