Stan lee...famous comic book guy,,, how is his health?

As far as I know, he's in pretty good shape for an 87 year old. He's out there filming cameo's for Marvel movies, making appearances on TV shows, even has a twitter account. He's doing fairly well as far as I know, but since I don't know him personally, I can't say for sure. But he seems like he has the ability to live to 100, or at least to his 90's. Even when he dies though, Stan Lee will never truly die, he will live on through his life's work and his memory will be kept alive by his fans forever.
