Most of the time when I'm out: my Android smartphone and wallet, my stethoscope, a pen torch, and the Oxford Clinical Handbook of Medicine. The latter three things because they live in my bag and it would suck if somebody in the street needed medical attention and I didn't have the basic tools.
I've always got my ipod and phone on me. During winter, I've got my slippers in the house. When I'm not in the house, I've got a huge jacket that has a hood that weighs more than my head (overstatement, but it's a real heavy hood).
When I go to school, I have my iPod w/headphones, mechanical pencil w/extra led (0.5 mm), my student ID, and my usb drive. Oh, and my books, binders, and notebooks.
Question to all those who have replied: Those of you who carry a pocket knife around... why?
Carrying around a blade of any kind is illegal in Australia and punishable with a $1000 on-the-spot fine, which actually causes problems for tradesmen who wear their toolbelts as a matter of habit for example. The rationale is that people are more likely to use anything at their disposal as a weapon, and since guns are not accessible to the majority of the Australian public, we've been seeing a spate of stabbings and slashings lately.
