Here's the stuff I carry:
My MP3 player. So that I can play MP3s.The problem is that while I'm jogging all this junk bounces around in my pockets. And then I end up running while holding my cell phone and MP3 player in one hand and my keys in the other, which means that I am woefully unprepared if someone were, for instance, to throw me a gold brick and shout "CATCH IT AND YOU CAN KEEP IT!"
My keys. So I can get back into my house before I collapse on the porch.
My driver's license. So if I get hit by a car they know where to take my unconscious body.
My cell phone. In case I fall into a tiger pit or something.
I am at an impasse. And because there are thousands of you insane joggers out there, I'm guessing there is some sort of technology or common sense solution to this problem. So... please enlighten me.
Side note: I noticed tonight while I was running that if I look off to the side instead of straight ahead -- say, to look at a bird which has startled up out of the marsh -- that my body keeps running without my eyes watching the road. Good job, body! That's a great trick.
