I know you think us adults are idiots, (I graduated in 88 by the way) but we were kids once too. And contrary to what you may think, we don't forget what it was like. It's just that when you look back on it, you have a different perspective and when you have kids, you hope to god that they won't do the same stupid and dangerous things that you did when you were young.
I wonder now how I managed to take a 3 hour hike up a rocky mountain trail at 3 am while on acid without breaking my neck. And jumping into a river and riding the rapids under the influence was pretty stupid too.
So just take a minute and think about things before you do them. You can still have some fun without getting yourself killed, paralyzed, or infected.
