Ya, the hero died at the end. I kept expecting him to come back to the very end.
EDIT: edited due to downvotes. Come on!
Roddy Piper has passed. Apparently, many professional wrestlers die early.
Is that due to the prevalence of steroid usage? Do we know?
Given the prevalence of heart failure, I'd say that is almost certainly the primary cause, but it's a pretty hard-living profession where excess is encouraged in almost every way, which can be quite hard on the body generally. Joint replacements are very common - Hulk Hogan had both hips and knees replaced in his 50's as an example.
I think that it's a pretty grueling vocation.
John Oliver actually did a piece on it, and that was fairly revealing[0].
