Kaeberlein's stated focus on signal versus noise
The description presents Kaeberlein as a gerontologist with more than 250 research papers and nearly three decades studying what slows aging. It says he wants to separate what is real in longevity from hype and to explain how to tell a real expert from a talking head. A chapter is described as covering how to spot longevity misinformation and a shift back toward science. These are topics the description says the episode covers; the video and transcript were not reviewed.
