I've been thinking of why I like to play sports. My #2 reason was: They provide a social "fix."
I'm addicted to other people. I like them. I need them. Solomon said, "Two are better than one..." I agree, and I like an addict, I need a regular "fix" -- a social fix.
Some sports only take a pair of players, others require teams. Friendly competition and cooperation enhances the enjoyment. Sports give you something to do with other people. Something fun.
I don't like being alone for long periods of time. I spent 1/2 day alone once... in the early 70's... in a redwood forest. Then I hiked back to camp to my travel partner. Then we got bored, so we drove to town.
I like being around people, but I don't like sitting around for hours on end. I'll sit around and "visit" a while, but then... really? Can't we do something? Play something? Do some sports? (I might even help you do some chores. Let's just move!)
Playing sports with friends means that along with the exercise you get some laughs. You share some stories. You find out what makes the other person tick. You also find out how they handle pressure, and winning, and losing. You find out if they are honest. You interact socially.
Did I mention I like that aspect of sports?
Today I played racquetball with my nephew and his brother-in-law. They are in their late 20's or early 30's. (I'm in my 50's.) We had a blast. It was our second time playing. We played for two hours. They're fast. They hustle. We all learned to communicate better, play smarter, and we all had fun.
Just remembering some of the action eight hours later brings a smile to my face. We played hard: we sweated buckets. And we're already trying to figure out when we can do it again. Why?
Because sports rock! I have to say that some of my fondest memories in life involve good times, with good friends (and family), playing sports. It can be magical... and addictive.
