As a healthy happy person, no.
If I was terminally ill, suffering everyday with no hope, yes.
If I was elderly and had a good life, I would accept it is coming.
If I was elderly, crippled, and had nothing in life, then yes.
So really...it depends on a person's circumstances, however, I don't think anyone would post their suicidal ideation on a vegetarian message board in a thread that is focused upon one broad, informal, and simple question.
