Like a lot of people here, I have lots.

My interests move around among them from time to time (like visiting old friends

).
Motorcycling: touring on the GS and playing on the 315R. Been doing that since I was 8.
Music: playing guitar (and bass, banjo mandolin, congas, etc), and more recently modelling music in FL Studio. Been doing that since I was 15.
Dancing: I used to square dance (that's where all the girls were

), but later took up rock'n'roll, rockabilly and 'bug. Been doing that since I was 19.
Bushwalking: Started doing that when I was too young to remember. With the usual spin offs of course: camping, abseiling, canyoning and caving.
Four wheel driving: started doing that probably in my 30s.
Farming: been doing this for the last 5 years or so. Takes me back to when I was growing up. So much to do... no pressure.
Photography: started in my late teens. Used to take panoramic shots on a Kodak Instamatic and manually trim and assemble the photos.

That's how you make real panos!

Always been more into landscapes than portraits...
Long distance running: haven't done that in aaaaggggeeessss!

Started about 12, stopped when living in Sydney in my early 20s due to the pollution and the effect it had on my throat

. Tried to get back into again unsuccessfully a few times.
Computing: There was a time when computing was fun. I used to spend weeks making my old MicroBee do pretty mundane things by today's standards, and writing magazine articles on how to do it. It stopped being fun when windows took hold and computing became useful, and therefore somehow necessary.

I still spend a lot of time on one these days and occasionally get a little satisfaction writing little astro applications in VB.NET.
Rescue: Got into that when I was 25 and stopped for political reasons in 2005. Had some very unique and special experiences in that time and sad to stop, but there are some very ugly, unsavoury people in positions of power playing with peoples lives. I pushed as hard as I could...

I still do the odd bit of consulting for fire / rescue organisations and magazines around the world.
Learning: love it, in all its forms - except doing "mandatory" training on stuff that I know... suck eggs? again?!

I also enjoy training and teaching, but I have become very cynical about competency based training w.r.t poor assessment techniques and lack of RPL/RCC.
I could probably go on...
