Based on my day today, according to http://www.caloriesperhour.com/index_burn.html (www.caloriesperhour.com), this is how much I've burned. I just pulled a 10 hour shift working as a busy retail cashier, 9 of that standing. I move back and forth (making change and bagging items, some of them very heavy, ex: reams of computer paper). I weigh approximately 170lbs, 5'7.5", female, and between 27 and 29% body fat.

Does this look too high to you? I didn't think I'd burn that much while standing at work.
