I don't know; for me this isn't the same as Dio or Lemmy or Bowie. This guy was 57, and looked 47. Even Bowie, who looked 10 years younger than he was, knew something was off, because he kept a very low profile over the last year or so of his life...
Interesting thing, he was on tour and not feeling well, and was on a plane and had to deplane because he was feeling so bad; this just happened to UConn Women's Basketball Coach Geno Auriemma; I hope there's nothing to that.
