I recently lost my little brother, he was 24. When I say recently I mean very recently, so seeing this thread pop up is a little eary.
Let me tell you death is no Joke. Nothing could be worse then death, there is no coming back, that's it. I dont think people should fear it though - we will however I think, it can't really be helped i guess.
To the OP, you are thinking very foolishly. Let me tell you, you never think it will happen to you or someone you love untill it actually does.
You should be as careful with your health etc as possible. You may live till 90 or die tomorrow, but regardless, you should never be careless with your life or anybody elses for that matter.
Dont act as if you have no control over it though. You will die, but why would you want to speed up the process.
