I got out of the habit of wearing a watch when I was working at zoo jobs. It would get stuck on things, and it would get dirty and wet, and there was usually a clock on a wall somewhere, and precise times weren't usually that critical anyway. Since I didn't wear one at work, there wasn't much point in putting one on for a few hours when I got home and changed, and since I wasn't wearing one most of the time I mostly didn't on my days off either. And gradually all the batteries died and I was pretty much watchless.
I just put batteries in all the dead watches and started wearing them again. It's really cool. All I have to do is look at my wrist and I know what time it is. I don't have to dig in my pocket for my cell phone and push a button. It's so easy! What will they think of next?
