I agree that the moon cycles seem to bring out a differnce in people in general. I know there are times when I was working (and now that I just started again) that myself and the people I worked with could just tell without looking that there was a full moon out, just by watching and dealing with our customers. (fast food resturant, and now a cashier at Kroger's) We'd go out back when we had a moment, and there it would be....staring us all right in the face and turning everything a little wacky.
I would guess the kids are less aware of their own changes and might be less likely to fight the urge to get moody, whereas adults kinda have a chance to realize they are being a bit odd.
I also know that my cycles are different when there's a full moon coming around, hard to explain, just differences in myself that I can sense. I don't think its superstitous in the least.
I was doing a search and found this (mind you the search was on google..haha)
