Calling 35 years "a lifetime" is exaggerating. Calling 35 years less than half a lifetime is accurate, not minimizing. "Half his remaining lifetime" is probably true, and that's also a valid way to look at it. But it doesn't really contradict what I said, because what I said is true. ("Possibly all of his remaining lifetime" is incredibly cynical, but technically true.)
First off, it's not that cynical. Plenty of people die before the age of 60. Male life expectancy is 76, so 35 years is 70% of expected remaining.
Also, the point I was originally making, is that for most people the quality of life between 25-60 is far higher than the quality of life from 60-95. Even if he does happen to live to 95 and it's "only half", most people are going to enjoy age 35 more than they are going to enjoy age 95.
