A study of 479,000 adults found cyclists had 22% lower Alzheimer’s risk, 40% lower young-onset dementia risk, and measurably larger hippocampi than nonactive controls. Here’s what the data actually shows, the APOE caveat the headlines missed, and the negative RCT you should hold next to it.
In May 2026, three major papers landed on Lp(a) — the genetic cholesterol marker that 1 in 5 adults carry at risk levels and almost nobody gets tested for. Here’s what the new evidence says, what to do if your number is high, and the aspirin advice you should stop following.
I read a USA Today story this week about the rise of “biohacking,” and my first reaction was that it mostly got the vibe right. More wearables. More self-ordered labs. More biological-age tests. More longevity clinics. More guys showing up with a screen full of numbers and the feeling that they’re finally getting serious about
A lot of health advice online still pushes the same basic fantasy: that one big change is going to transform your future.

Many fitness tracking apps and wearables offer metrics — so many metrics, that it’s easy to get lost. scores for everything: sleep, fitness, training readiness, heart rate (variation) and many many more. I am a self-confessed data nerd and I feel overwhelmed by these metrics. I am trying to pay only attention to the things
I spent most of my life thinking heart disease was something that happened to “other guys.” I don’t have a family history of heart problems but obviously occasionally heard of cases. The older guy at the office. The guy who never exercised. The friend who lived on pizza and stress. Then I started looking at
Over the last year, I have been reading and watching a lot of health and fitness-related content with a focus on longevity.
