I hardly get emotional when I'm watching sports by myself, but when I'm with other people, I do the odd fist-pump and "Yessss" and *groannnn* every so often...lol.
Perhaps I am rather reserved compared to most people....I enjoy watching and playing sports, but I do realize that at the end of the day, it is just a game. It's that realization that helps keep me grounded.
Not sure what everyone else thinks, but I really do think that sports is an essential tool in developing the individual psyche- especially when interacting or relating to other people........................I won't elaborate any further as the bigger jocks might beat me up...lol.
