@ScientistMel I've had many head injuries. The 1st that I remember I was 7 the 1 at 19 caused amnesia. Crash tested 2 helmets after that. At 30 I got clobbered over the head and stuffed in the trunk of a car. The rental agency of the cars I guarding wanted to charge me the cost of blood cleanup in one of the cars I was guarding.
@ScientistMel I'm now 59, so I've lived past my life expectancy by 30 years
