ok man whatever, do nothing you want in your life in hope to stay alive for the longest time possible and if you can sick at 40 years old you will only be pissed you never did what you wanted in your life
I don't get why you get so mad, that the way I want to live my live.
Live your own life like you want and stop caring about what the others want to to with theirs 
i couldnt help but comment bc basically u were saying "Hey, my dad tried to stay healthy all his life
but he still died, SO, whats the point of trying to "be as healthy as possible when anything can happen"... What can i not do living a healthy/smart lifestyle that i couldnt do just "being careless"?
Dude it doesnt mean seclude yourself from society and live in a plastic ball... its just not doing things that arent beneficial-- a smoker can live to be 80 and a non-smoker can live to be 80... who do u think will be healthier - meaning more happy, energetic, and overall feeling of well-being? sounds good to me
