It's laughable how some of you ignorant fools believe there is necessarily a direct correlation between body weight and longevity as if there is some magic weight, say 175lbs, a man should weigh to ensure life into his 80s.
Well, let's ask Nasser...oh wait, we can't.
It's not necessarily the weight, it's what he did to get to that weight. The food, drugs, and training. Plus, he has had two hip replacements. Nobody knows how his heart and kidneys are. A lighter weight, and more focus on other things outside of what he was doing before, might help him.
It seems like LE and bbing were all that he did. I wonder if he could just open up a PI business, something to keep him occupied for the time being.
