I'm glad that by using and defining that word "predisabled", I have raised your consciousness enough to consider your own mortality and the fact that your vision, hearing, dexterity, mental acuity, and memory are going to degrade as you get older.

Not everyone is predisabled: many unfortunate people won't live long enough to suffer the consequences of old age. But I'd rather not die before I get old, myself. I certainly hope I'm predisabled instead of short lived, myself.

It sounds like you're the one who needs a counselor if you're so depressed and having such a hard time facing the fact that you're getting older every second, until you die.

If you're designing user interfaces, you might want to seek out help for an accessibility specialist.
