My Grandpa smoked 6 PaD & cut his leg @ 93 YO & was forced to go to emergency was admitted,caught a staph infect & died (in the hospital)from it. Their contention was that if he didn't smoke the staph would not have killed him. I contended that if he didn't go to the hospital,he would not have contracted staph. BTW,he also drank a half pint of whiskey a day LOL. That was in 75. Later
