most teenagers who self harm do it not to commit suicide but because either they want the attention or because , ironically, it's the only thing that makes them feel alive.

most old people that reach the age of dependence, most of their major organs have started to fail any way. and more than likely will be dead or severely debilitated. if as a very old man i will one day choose to take my own life because of senility, well the final choice should still be mine.
