I love soccer! Its a big mental game as well as a big physical game. You absolutely have to be in shape to play and do well. Its a challenge ecspecially if you understand what's going on while you're on the field and realize its more then just kicking a ball around. Soccer is probably one of the sports that ivolves the most teamwork.
Oh.. and about all you do is kick all ball around a field. All sports can be put that way. Ecspecially if you've never played on a real team before.
