Anybody and I know there are a few out there living with constant pain not the mild kind the lot that take meds that thin your blood to the point if you were ever in a car accident you would bleed to death. Dick I was was told over the last 3 years went from doctor to doctor to have them scratch thier heads and say DONT KNOW..yeah he was 71 and a race car driver. he also had the rough stuff too the emotional stuff his granddaughter that he loved dearly died at 16 and he couldnt ever get over that hurdle.
