There is a small article
here not a lot of facts other than a death was confirmed. One poster on the article said the man suffered a heart attack.
At 60, he was way too young but if I ever had to choose between dying an old man confined to a hospital bed or while I was still able to do something I loved then I know what I would choose.
If it was simply a heart attack, maybe the family can find a little comfort he knowing the man died while participating in something he enjoyed
