As eWN community member Greg Beck noted earlier today here on the website, TMZ has posted a video of Jerry "the King" Lawler wrestling even after he suffered a heart attack in 2012. Lawler is 64 and was in Queens, NY this weekend. He competed in a tag team match for JCW Pro Wrestling. He was said to be in great shape (even hitting some dropkicks) with no indication he had a heart attack.
Lawler's heart attack occurred during a broadcast of Monday Night RAW shortly after he had a match that same night in Montreal. He almost died, but has no plans to retire. In fact, he has more matches lined up for this summer.
In an update on Greg's report, here is a video of the match:
