I'm definatley number 1 minus the drugs (I'm 14). I would think you could tell by the music they are playing. I play things like rock, grunge and alternative and I'm really like hey chill out man. But my friend Kevin plays progressive metal and he is more to the second. He can argue the hell out of his opinions. Jazz, gospel, blues and rock seem like they would have drummers that are more chill while people that play metal or are everything drummers would be more uptight.
