For some reason, some days I just don't get hungry. I can go on a little breakfast until 10PM, and not even begin to want to eat anything. My parents say that this will ruin my stomach. True? Sometimes I lose track of time, and there are none of those stomach rumbles to remind me that it's time I go out for some lunch. I've always been underweight from when I was a ravenous little kid, that got anything to do with it?
