I watched an interview with britain and
the worlds oldest man. 112 at the end of the month. Still tack sharp and smiling. He doesn't have a specific diet and says he ate what what put in front of him with minimal questions asked.
It's clear however that he didn't adopt my 27 stone pie diet that i had up until last year. He's had a well travelled life and didn't worry much about anything that could happen. I suspect the media couldn't sell many papers to this man
He only drank on special occasions and it was unclear as to whether he ever smoked, although most did in those days. Amazing really. I think learning to deal with stress and managing diet are the two biggest factors to longevity and quality of life given the genes you were born with.
