Dear Peter Singer:
1) Place plastic bag over head
2) Tie plastic bag firmly around neck
3) inhale and exhale often
4) Close your eyes
5) Go to the light and meet your maker.
That is almost impossible to do. Try it for a few breaths and you will see. I offer him better advice.
1. Go to Wal-Mart and buy their cheapest 12 guage, single shot shotgun and a minimum quantity of shells, you only need one and it doesn’t really matter if it is fine birdshot, buckshot or anything in between.
2. Load shotgun, cock hammer, place muzzle in mouth and pull trigger.
For extra points sit on railing over large river with back turned to river and proceed according to number two.
For maximum points look up McCall, South Carolina on a map and just go there and start telling people they should all kill themselves, your estimated life expectancy will be five minutes max.
