Carl, excellent interview of Aubrey de Grey. You asked perfect questions for this expert. I'd like to dispute Abrey's dismissal of diet as a potential way to add 30 years to one's life. I believe that following a paleo diet (and lifestyle*) versus a lifetime of the SAD can certainly result in a +30 lifespan for some. Perhaps many could benefit that much if we decentralized food production and moved away from highly-processed foods.
*Ok, that's a big caveat, but it complements the diet part and is still distinguished from Aubrey's "medical" solution.
Awesome show, Carl.
