The 44-year-old ex-heavyweight champion is in bed by 8 and often up as early as 2 in the morning, at which point he takes a solitary walk around the gated compound in the Las Vegas suburb where he lives while listening to R&B on his iPod. Tyson then occupies himself with reading (he’s an avid student of history, philosophy and psychology), watching karate movies or taking care of his homing pigeons, who live in a coop in the garage…As part of his cleaning-up campaign, he has been adhering to a strict vegan diet for nearly two years, explaining that he doesn’t want anything in him “that’s going to enrage me — no processed food, no meat.” He says that he can no longer abide the smell of meat even on someone’s breath…If Tyson misses his high-rolling days, he isn’t letting on: “If you make a lot of money, you end up being around people you don’t want to be around,” he says. “Guys on allowance. It takes years to gather the audacity to get rid of them.” [NYT]
