Bonsai (would have been a pleasant, life-long hobby if only I could remember to water them)

Line-dancing (boot-scooting)- I got the video!! (just that my lounge room wasn't big enough!)

Playing some sort of musical instrument (now, c'mon...who hasn't tried that one?)

Various sorts of fitness programs like walking/swimming/weights (maximum interest period = 6 months)

Calligraphy (now there's a useful skill-NOT!)

Teapot collecting (I have 3)

Dungeons and Dragons (I was very young and reading J. R. R. Tolkein at the time!)

Marriage- yep, I was once legally married to a (gulp) man for a whole 14 months! (and I'd just like to point out that that's more than double the amount of time spent on any individual fitness program and therefore constitutes a pretty good effort on my part!...and in the end it turned out I was a dyke after all!)
