Sleep may not prevent senility. The evidence is inconclusive.

I have a fear of insomnia. I am afraid that I will listen to other people talk about their insomnia and catch it from them. I am afraid that I will forget how to sleep and find myself miserably watching Shakeweight commercials en espanol at 3am. That Keanu Reeves will catch me.

So if you get insomnia, don’t tell me about it. And I won’t tell you about my senility. Even though I lost my security badge twice this week, then found the second lost one and, thinking it was its replacement, tried to use it, only to have to get a third one because that one had been deactivated.
