Vegan Distance Runner vs. Meat Eating Natural Bodybuilder in Health & Nutrition Programs Posted June 29, 2013 When you start to look into longevity, and even more so when you start looking into the lives of centenarians you will start to see a common factor in their lives: WALKING. Seems to be about an 30-60mins a day for most. There has been the odd runner, I can't recall his name but there was a Japanese man that when he was in his 90's he ran a 14 or 15sec 100m race !! He's still alive and has outlived ALL of his doctors, and from memory stopped eating dinner in his 80's (his doctor told him that would kill him, but his doctor since died). Wow! That's...just wow! If you think of his name, let us know. I'd be interested in reading up on him more.
