#2 Wrong. You just have to be a little mentally ill. I never really enjoyed baseball much when I played outfield. One year I played on a team that had a very good 1st string catcher...and no backup. Kind of a problem when the 1st stringer tore a groing muscle. Yeah, still makes me wince thinking about it, too.
Coach asked for volunteers. I raised my hand, and after about the second or third practice, I was hooked. You're in on every play, you call pitches, can set the defense (depending on the team and coach), and there is a far higher mental challenge to playing the position than anywhere else in the field.
I even recall games where I might feel a little run-down, lethargic, whatever. Take that first fould ball off of the helmet, and that wakes you up in a hurry!
BTW, I played several sports year-round, usually was one of the faster baserunners on the team, and I was in very good condition. I actually had, at one point, 25" thighs and a 24" waist. Crouching behind the plate and playing a lot of running sports (soccer, basketball, whatever) will do that.
To this day, I will watch a game, think what pitch I would call, what plays (if any) if someone is already on base, etc. Used to attend games years ago with a neighbor who had played professionally, and we could sit and talk strategy and the mental part of the game all 9 innings and never be bored.
