and while you're at it, stop watching the rest of his fights as well. what are you talking about? would YOU meet mike tyson in a back alley even today? I'm assuming not.
just because someone loses weight it doesnt mean they are sick. He hasn't lost a lot of muscle, he looks healthy. He lost weight but if you go through what hes going through you'll lose weight.
looks like most of the weight he lost is in his legs. he wont be boxing again because his center of power is gone.
He's doing a reality show in which getting back in shape is part of it and in the finale he would be fighting a MMA fighter who's name would be held until the end. They have yet not decided if it would be a boxing or MMA match.
