Oh... I have lots! All have been dominant at some point in my life

...
Astronomy... obviously...
Motorcycling... too old for motorcross and enduros these days so I tour a little on my BMW R80 and I have a Montesa 315R trials bike for play


.
Music... I have several guitars (a classical, a steel string, an acoustic bass, and electric and an amp), blues harps, occarinas, conga drums, clap sticks and an egg

. I'm not playing often ATM, but it comes and goes.
Computer programming. I used to write articles about programming Microbees back in the good old days (basic, fortran, pascal, assembler and machine code). I dabble a little with VB these days... hence AlsReticle, etc.
Bushwalking, abseiling, canyoning and caving. Don't do as much as I used to as I now have a....
Hobby farm!

Well its a place for my observatory out of town

, and it has room for the girls to own and ride horses, and despite all the weeds that keep me busy chipping and spraying, its great!
When I was little I used to collect tractor pamphlets... I don't do that any more. I have an old IH 434 and few implements to keep me happy!
I never have a shortage of things to do...
