Fighting aging with evidence and experiments
Elaine HeFounder · Writer · Community leader
Hi there, I'm Elaine — a health nerd and tech founder.
I grade the evidence carefully, I run protocols on my own body, and I build the tooling.
( Intro ) I'm not a doctor and not a scientist. What I have instead is my own data, AI to actually read the research, and a stubborn refusal to accept that health advice has to be guesswork.

Building &
Signl
An evidence-graded protocol library. Every protocol carries two scores — one from published research, one from what thousands of real people report — and then it helps you run your own two-week trial to find out whether it works on you. Launching October 2026.
Community &
Don't Die SF
One of the Bay Area's most active longevity communities, which I co-lead. Tech talks, workouts, recovery sessions, and dinners where founders, scientists and clinicians argue about what actually works. Part of Longevity Cities, a global community across 11 countries.

Field notes
A protocol I ran, a claim I graded, a result that didn't go the way I expected — and sometimes the bigger question of what any of it is for. The null results get published too; that's most of the point.
Career &
Record
Ten years building data and consumer products before turning the same habits on my own health.

One piece a month, when there's something worth sending.
I am not a doctor and not a scientist. Everything here is my own experience and my own reading of the evidence — not medical advice.
