One thing I've found that I can do that I really enjoy is rereading my own writing, earlier stories and novels especially. It induces mental time travel, the same way certain songs you hear on the radio do ... the whole thing returns, an eerie feeling that I'm sure you've experienced.

DickWell, I hate to admit it, but it is possible that there is (one) such a thing as telepathy and (two) that the CETI project's idea that we might communicate with extraterrestrial beings via telepathy is possibly a reasonable idea--if telepathy exists and if ETIs exist. Otherwise we are trying to communicate with someone who doesn't exist with a system which doesn't work.
