Replying to @a16z
@a16z State of Longevity report is out! @evajsteinman and I surveyed 500 Americans to predict what's next. We're also interviewing people at the cutting edge of health & tech about what they do themselves. My interview with @hubermanlab is out today.

AI body scan in Korea says my musculoskeletal age is 3 years above my chronological age. doctor at @yonsei_u pain clinic said every C-suite exec he treats has my reversed cervical curve pattern (flattery?) if you're on X 🤓 odds are you've developed tech neck too, from years of craning over desks. ironic and mildly shameful, since I'm building a posture wearable @lineaposture. now I'm even more evangelical about posture + locking in (even) better habits. more on this soon.
