Yea, everybody knows you can
die if you do certain things. You can die in your
sleep, you can die even if you're not trying to get yourself killed. What does anybody who's still alive really know about mortality though? If your
friends or
family died in a car accident, they would be the folks who know about mortality and not you. I doubt anybody who claims to know all about mortality from seeing horrific accidents has had an opportunity to talk with any of the deceased about mortality, therefore you're full of shit when you preach about it, you don't really know shot like the rest of us.
The girl must know it all about what
death is like from seeing some
bad accidents since she's preaching to everybody how they should live their lives the
way she lives hers. Any slight deviation from the way she lives life will be considered reckless and adolescent minded, watch out! She's a mortality expert!
