Well definately not while skydiving unless!! Well at the DZ it is known if something goes wrong and you using the club equipment loose the chute as the packers aren't to happy if you get blood on the shoot and then just go down and take one for the team. Not my idea.
Maybe a high speed car accident like 120MPH or something it is fast,suppose could be messy and well you gone before you know it.Other than that a peaceful death in one's sleep will be a winner after a good night.
Will say and do as I please.
