Episode 52: Very old people and "Blue Zones"
What’s the secret of living to 100? Well, it might be living in a “Blue Zone”: one of the handful of places around the world where there are apparently loads of centenarians. Except, as has been argued recently, Blue Zones might be a load of nonsense. In this epside of The Studies Show, relative spring chickens Tom and Stuart look at some of the recent controversies in demography. Is there a limit to the human lifespan? Did someone really live 122 years? And how could researchers not have noticed the glaring problems with the whole idea of Blue Zones? The Studies Show is brought to you by our new sponsor: Semafor. They’re a purveyor of high-quality newsletters offering in-depth information in digestible chunks (and they happen to be Tom’s employer). This week, we looked at Semafor Technology, in which Reed Albergotti interviewed will.i.am on AI and the future of music.
