music, generally. Singing is good wherever you do it, whether in the church choir or while mowing the lawn with your iPod on. I started bass guitar around this time last year and just messing around with 12 bar blues and three chords can be good fun (although the number of bars varies by how rigorously I count). Dancing is also good. I think you should try to dance as often as you can, whether just getting down to the grooves with your iPod or doing scottish dancing, preferably in a big ceidhli.
How can you feel when you're made of steel? I am made of steel. I am the Robot Tourist.
