Interesting... I'm less interested in his physical appearance and what he may or may not be doing cosmetically and more interested to see if, in fact, he lives a super long time and stays healthy.
There is a group of us doing it and some are between 80-90 now (and in amazing health!), so he's not the oldest. I think many started at some point in the 90s. In the study group at WUSTL (not CALERIE study), they found zero plaque build up in any of the participants, even in one person who was around 80 at the time (if I remember correctly..) Plus hearts that functioned about 20 years younger than their biological age. Gene expression taken from muscle biopsies were also close to 30-year-old controls than 60-year-old age-matched controls. There were a lot of genes involved in longevity that were significantly up-regulated.
But yeah, still, nobody knows if it will work. It's a really long experiment...
