Indeed. Personally I am confused by those wishing to die in their sleep. I'd prefer to be totally awake, cognitively aware that I'm dying. People think I'm joking when I say I'd like a violent death, if the alternative is Alzheimer's.

The trouble is a) knowing that I have it and b) having the drive to annihilate myself before I no longer can do it myself. Fortunately I live in a state where suicide is legal and available by pill, and that's a great option if I can't build up the drive to rig my death some other way.
