Lawler is smart enough to work his matches in typical Old Timer style where he takes minimal to no bumps, and I would be far less concerned with him in the ring compared with anyone else in his age range. Plus while he did almost die in the ring, it was more of a shit happens thing (possibly genetic since his father died young from heart issues) rather than the result of decades abusing his body,
Ric's probably done more damage to his body outside the ring than he did in 40 years of wrestling and a plane crash. If Mark Madden is to be believed (I know, I know), Ric's back to getting drunk on a regular basis, which makes this even more of a bad idea.
