Understanding College Kids...I just can't do it.

Do you remember when you went to school? I remember when I was in my first go around in school back in 1983-84. I lived on campus at Northern Oklahoma College in Tonkawa. I was a fair student and was wrapped up in all my different activities. I was in charge of the campus radio station and I had friends but very rarely did I stay up real late. I mean real late for many of us is midnight. But nowadays I guess many of the kids stay up well into the 2-3am range. I just don't understand it. What good is going on during those hours and what ever happened to a good night's sleep. My son is one of those "late night" people and I just don't get it. It really makes you worthless the first part of the day. I can understand if you were doing shift work or something like that I was that way once. But just to stay up until?????? I just don't see there is any good in this behavior. Does anyone else feel this way. I feel like a person has a better chance at success in life by getting good amounts of rest and being productive. What productivity comes this early in the morning hours. Any thoughts?
