I'm young right now, but I'm both intrigued and scared about growing old and losing my grasp of my mind. Awhile ago I've decided upon a signal for myself that, should I see it, means "you're crazy and you can't trust yourself". Hopefully I'll recognize it when I see it later, and also have the forethought to deploy it in time. I doubt it'll actually change anything (i.e., if I have Alzheimer's, I'm unlikely to remember the signal anyway and act accordingly) but I like to think of it as a neat little experiment on myself.
