Have there been any MMA fighters who have died suspiciously young because of heart attacks? Maybe the sport is too new. I suspect the fighters in the first generation of MMA fighters - roughly the ones who started competing between 1993 and 2002, will start having problems soon. I hope there won't be too many casualties, but one look at the number of pro wrestlers who died before 50 years old is very frightening, especially the wrestlers who were at the peak of their career in the 1980s. How do you suppose Arnold Scwarxenegger is still not only alive but still active having been Governor of CA and now is back making movies in which he still has huge muscles? Sylvester Stallone seemed to keep getting more muscular the older he got. He's still massive in his 60s! How do they stay so healthy?
