A man walks home late at night, and suddenly saw an 8-year old boy with a smoking cigarette, drinking from a half-empty bottle of scotch. Outraged, he screams at the kid:
“What the hell are you doing? Those things are very bad for you health, and you’re far too young to even consider this!”
“My grandfather lived to 100 years”, – replies the kid nonchalantly.
“Err, and did he smoke and drink all the time?” – asks the confused man.
“No, he always minded his own business”.
