What are the best resources / who are the best thought leaders in the field of longevity (living longer and healthier)?

Founder of venture DAO Chainforest (www.chainforest.xyz). Also treasury Co-Lead @ FWB. Liftcaster. Fashioncaster. Dadcaster. NYCaster. NBA Caster.

Not tech-aligned but Dan John and Original Strength are incredibly orientated to longevity.

Dr Peter Attia is worth checking out. He has a great podcast that often covers longevity.

@barmstrong co-founded a company focused on this called New Limit. A lot of the talent is still siloed in academia. 

More scientists are spinning out to commercialize their discoveries but there is still a lot of friction in this pipeline, which is creating a big gap between the states of discovery and development.

Co-Founder at sablier.com, and open-source developer. I have a broad range of interests, including longevity, epistemology, physics, and psychology.

@prberg might be able to suggest some good ones

I think this is the frontier atm.
