I knew a fair number of kids who were raised in a very, very strict household...often a very religious household (Mormons, mainly). Once they were on their own, and finally could be a bit wild as a kid is often meant to be, they went a bit too wild. Several got alcohol poisoning and a few died. They were just kids being kids. I always stayed out of the hard-core drugs but was friends with many, many from "perfect" households who did not.

I had a wild streak myself and had parents that allowed it---to an extent---which got it out of my system early. I was the kid sneaking beer into JR High and drinking it between classes. By the time I was 21 I was often a DD, by choice. I truly believe having a somewhat undisciplined childhood is a good thing, for a lot of personality types at least.
