Used Watch

I used my new watch yesterday. It occurred to me that if I just run the stop watch all day, then it will count my calories all day for me too.
It was a little bit disconcerting actually. I did eat breakfast before school. And I did work out, but at the end of the workout, I had only burned about 400 calories and I thought something like, "Well, if that's all I burn in a medium type workout, then I must not be using as many calories per day as I thought. I'm only going to burn around 2200 kcal today."
So in the early afternoon when I was getting hungry and I hadn't eaten since breakfast, I checked my watch and it said I had burned over 1600 calories already. I hadn't even done anything since breakfast! I thought something like "Man! I'm gunna die if I don't hurry up and eat something. I can't believe how many calories it takes just to continue living while I do nothing."
Fortunately, I had some Cliff bars and a Lara bar in my backpack, so I didn't die. I wished that I had a bottle of water in there too, because then I could have not-died in better style, but the empty bottle I had was starting to get a little gross, so I didn't want to fill it again.
I continued to not do anything active the rest of the day and I lived like I normally do with the exception of wearing my watch and the chest band. I also wore it to bed. It's amazing how many calories I burn while I sleep.
The watch also tells me continuously what my heart rate is. That was interesting because I thought I should have a heart rate of around 65 all day except when I exert myself. It turns out that 65 is only good for a resting and really doing nothing heart rate. An awake and moving around doing nothing heart rate for me is closer to 90. Before bed, while I read my scriptures etc I checked my watch a few times and my heart rate dropped below 50 sometimes.
So my calorie reading this morning was 3300 kcal. !!!!!!1 My metabolism is higher than I thought. I don't know how I cram that many calories into me every day. I also don't have any idea how many calories are in most foods, so I don't really have that much frame of reference to justify my surprise.
