There have been 4 momentary blackouts this evening, where the power has gone out for only a fraction of a second. Every time it does that, the computer speakers make a rather loud noise. It so happened that when it happened, I was lying down, trying to get my shoulders and hands to relax.

Strangely, the surprise of the blackouts, and the resulting relaxation of the tension just after them really seemed to help. Sure, I could try exercise, eating right, or the love of a good woman, but maybe all I really need is a less consistent power supply to maintain my health.
