Backpack

I use a backpack to carry my stuff with lots of pockets (started carrying one in college) to put my cell phone, pda, wallet and other stuff like a coin bag, eyeglasses, notebook (the kind ya write in with a pencil), radio, a few protein bars, and a small first aid kit. And I am 54yrs old.
And here a comment for your "How Geeky is too Geeky" When I am at the checkout at a store and while the store's computer is processing my credit card I say "working...working" like the old Star Trek computer. I get some strange looks from the clerks!
