>You can always kill yourself.

Mostly technically true. Once you're locked in, or paralyzed, it becomes quite more difficult.

But right now, most suicide methods that are available live in the less pleasant octants of the availability/suffering/uncertainty space. We used to have some fairly pleasant -- by comparison -- deaths available to us but they're getting harder to access, leaving the nasty route behind. Coal gas? Gone the way of Plath. Barbiturates? Out-moded now, know a vet? It isn't like you can nip down to the corner for some laudanum like back in the day.
