What kind of hobbies or activites do you do and why?

Of course, the title is a little explanatory but I'll expand.
I know that one of my reasons for my drift away from RMRK was an eventual weakening of interest in RPG making as other hobbies grew in sophistication and potential fun. Of course, this forum isn't all about RPG making, as we have a very strong community here as well. With that in mind, I'd like to ask what you all do with your other free time. It can be outside, inside. It can be on the computer or underwater, though perhaps both or neither.

Second, why do you do it or why does it catch your interest?

Not to be self-serving, but to start of the thread I guess I'll go first.

Warhammer/40,000: A table top miniature wargame and hobby. Modeling and painting the miniatures, as well as designing background "fluff" for your army and its characters make up half of the hobby. The other half is, of course, battling in lengthy games against friends. This originally grabbed me due to a fondness for painting and little green army men, though it's also good for socialization and a great alternative to video games with friends.

Various video and computer games: PC, PS2 and DS. haven't played as many lately but the general entertainment value is what makes games what they are. The sophistication of an RPG storyline and the thought involved with strategy games also adds to their appeal.

Airsofting: I turn away from the intellectually themed, though still fun. Boils down to shooting at friends with pellets while pretending to be in a paramilitary or military unit. Fun stuff, not all that painful in the end.

Drawing/Painting: Not so much on the latter lately, but drawing is what really started off the rest of my hobbies. The joy of creating with the appeal of something cool or meaningful is definitely the pull.

Warhammer 40k every now and then. DEATH TO THE FALSE EMPEROR ect ect.

I haven't been airsofting since our unit disbanded. :< We were beaten in a tournament in Austin, third place for Foxwood Rifleman Division I!

Drawing is my whole life.

Playing Bass guitar.

That's about it.

Writing music - Because it's fun, and I don't think I could live without it.
Gaming - Because I like to be in different worlds sometimes.
Reading - Same as above, but I also appreciate a well put together sentence.
Writing - Getting thoughts down on paper is a great release.
Walking - I like seeing the world.
Talking with friends - Humans are social beings.

What he said minus writing music =o 

Edit: I knew there was a reason I liked you ;P

Video games, for the same reason as Holk and LadyJ.
Writing, because I love creating and telling stories.
Game designing, for the same reason as above.
Drawing, something I've recently picked up because I love creating things.
Martial arts, because despite how nerdy I am, I'm still an active person.

Probably forgetting a lot, but this is what comes to mind.

Web design - my art. Love learning new things everyday and really you can do anything.
Web development - just starting out using php and mysql but its a whole lot of fun!
Sports - obvious, they're fun.
Gym - Good use of my time, getting bigger ;p
Guitar - Not any where near good, but its a blast trying.

Guitar - I <3 this thing. There's a butt-load of things that I've tried and haven't tried and it's an adventure just finding new things and having pride in myself.
Games - Games are good. You use up time that you don't want. You feel good about other people feeling bad that they lost or that you're just plain better than them through hours of grinding. It's just good. XD
Dancing - I haven't danced in a while, and I was never really good with style so I was able to express myself completely through it. But it was fun doing it with my friends (as a Korean, it's obviously breakdancing).

Writing music - Because it's fun, and I don't think I could live without it.

What she said plus writing music =o

It's great to see all the creativity here
I left out dancing, because I forgot, but Moo reminded me. It's similar for me though, in that it's fun but I haven't truly done it in a while.
What's also interesting are the different reasons we like doing the same or similar things, like gaming. Some like being taken to other worlds, while others enjoy competitive aspects. I guess that depends on the genre and type of game though...

Scripting is a big one these days, because I guess I love seeing how the work I do translates into features in other people's games.
Gaming, of course. I love games - RPGs and Fantasy games mostly, for the same reasons as other people have posted.
Reading - still one of my favourite things to do
Writing - I'm a bad writer, but I still enjoy doing it occasionally.
Watching TV - I'm addicted to like eight shows
Musicals - just recently I've started really liking musicals. I don't know what it is about them; maybe it's the fact that it's basically just a music album with a story. I still despise West Side Story, naturally.
Walking - I love walking; it's so peaceful. I usually walk anywhere between 3-8 km a day when I have the opportunity.

I abandoned my other hobbies for WoW.

Okay, serious response now.

Writing/playing music - my life, my potential career, my passion. i dont think i've ever loved anything or anyone as much as i love music.

Video games - takes me away from earth. Can be a good or a bad thing, lol

Reading - not so much nowadays, but back in the day it was hard to spot me without my nose pressed between a paperback.

Hackeysack - the only "sport" i'm actually good at. i just love its portability more than anything, really

Papercraft - i used to LOVE origami as a kid, this is a step up for me. i love recreating my favorite video game characters and other tchotchkes =p

There are several other hobbies i enjoy doing on occasion, like Photoshop, home architecture, drawing, photography, D&D, programming, and the like, but i don't do them enough to really go into detail about them. Point is, i keep myself busy =p
