By 'living suiciders' I mean those who give indications of committing suicide but not potray suicidal behaviour. This is generally done to threaten or to freak people out or simply for the fun of it, to see how people react; or of course in some rare bizzare cases as an elocution piece.
For those few here is a compilation from a simple Google search
12 common ways to commit suicide:
12. Vehicular Impact
Results From Failure: Permanent loss/damage to organs.

8. Exsanguination (usually slitting the wrist or throat)

Not : But of course : This is not an encouragement to those living suiciders but a mere reminder that there are a lot of things that can go wrong in attempting suicide. And probably your life is a happy one till you attempt and then it would not be worth living but you would be stuck in the hell that you would have created for yourself.
