Being basically retarded and having learned this fact long ago, I now stick to certain procedures to avoid things like "washing the phone".

The relevant one is: if I'm in the apartment, my pockets are empty. That's a rule, and I have a spot set up specifically for everything to go when I start emptying them.

I figure that when actual Alzheimer's starts to kick in, I'll have a head start on it and nobody will notice for a while, including me.
