The OP has made a highly personal decision, and we should accept it as a fact without need for justification, nor try to quote statistics in an effort to change his mind.

Fact is that statistics are not destiny, and there are myriad variables that affect each person's risk level, and likelihood or extent of injury. Then, even with all manor of actions to tweak the odds, there's also an element of luck.

So, while I offer my condolences to the OP for the prior injuries and pressures that lead to his decision, I also understand and wish him the best.
