I shouldn't say this on a joke thread, but I'm going to.
My Dad was a macho, old school man. I heard him say countless times when he learned something he did was unhealthy, always with a grin on his face "oh well, if it kills me, it kills me".
When he died of preventable, lifestyle-based reasons a quarter century before his body was due to wear out, among other damage done, he left devastated grandchildren behind.
My 5 year old nephew, who couldn't really comprehend what was happening, asked his mom if he should hit himself in the head with a hammer so he could go be with Grandpa.
Imagine dealing with the grief of a lost parent and suddenly you're terrified for your baby boy harming himself. It almost destroyed my sister.
I know if my Dad had been able to see the reaction to his death, he would have decided he probably could have done without daily ham sandwiches for lunch and bacon for breakfast on the weekend. He didn't drink or smoke, but his diet was atrocious.
Again, sorry to piss on the joke thread, but I feel so strongly about this subject I was compelled to respond. I'm not trying to tell anyone what to do, or judging, just sharing some personal pain that may provide some perspective.
