Re: That Old Saying... "Growing boys need their sleep"
If you stay up later you obviously are going to sleep in later. It's not a disruption. As long as you get a decent amount of hours 6-10 ish you're fine. You can't expect to wake up at the same time in the morning if you stay up later because you body requires a certain amount of hours of sleep so it has to make up for the lost hours you spent staying up.
