A valuable skill for twenty-first century humans is the ability to be alone. The ability to be comfortable alone is especially useful for aging and retired people. Once you get old and run out of steam, unable to attend parties which begin at 9 or 10 PM, you stop receiving invitations. This is not a problem. It's part of the natural order. As ones ages, the body slows down. One has lots of time alone to contemplate, or to get to know oneself, like the Oracle at Delphi said to Socrates, "Know yourself." Soon death happens. The body becomes a corpse. Why not make use of valuable time and try to figure out what's going on? This is your last chance to stop being neurotic.... ooooooogah!
