Track What Moves The Needle Without Wasting Thousands

I spent $3,143 testing the gear so you don't have to:

• See which devices and tests are worth it (and which are a waste)
• Get the exact testing order I follow
• Learn to measure only what changes a decision

A field-tested guide to choosing health-tracking devices, built after 8+ years and $3,143 spent on bio-age tests. It maps 8 goals to the right device, compares smart rings, HRV and brain tools, and 18 red-light devices, then ranks what to test first (wearable, genetics, blood, DEXA, bio-age). Inside is the 7-kit bio-age experiment run on a single blood draw, the 13-year spread in the results, and the kit that won.
