I played a bit in grade school and high school whenever I was forced to. The things I remember are 1. being really lousy most of the time and 2. teammates who were WAAAY too into it, a toxic combination. (Yo, Leighton, you’re going to be a struggling-to-survive ditch digger in a few years; volleyball isn’t that big a part of your life, mmkay?) P.E. was almost universally about savage, vicious, adrenaline-soaked competition, sometimes with a crowd on hand screaming for blood. This did not give me a positive opinion of P.E.
So the heck with it. I have my treadmill and I’m happy with it. And the only thing that’s the least bit surprising about that is that it’s not “Nordictrack” or “elliptical machine” instead of “treadmill”*.
As for watching, my tastes have changed vastly in the past couple of years alone (let alone since childhood), so a brief current tally:
Football (college & NFL): Used to be something of a fan…I remember the Broncos against the Packers in the Super Bowl and hoping really hard that this would be the time…not so much now. There simply have been too many unsatisfying results for me to keep caring. Patriots fail to complete 19-0, ensuring that ESPN will keep blathering about Mercury Morris for the next 50 years**. Slimeball Art Modell rips the heart out of Cleveland and is rewarded. Barry Sanders retires in disgust. Bengals see their one shot at happiness taken away by a jaw-dropping miracle drive. Seahawks the victim of possibly the most brazen robbery in history. Michael Vick crashes and burns. Kurt Warner sees his career sink into the abyss an inch at a time. As for the college side, not much has changed for Hawaii, well, ever: They can be truly awful, they can have flashes of greatness against weaker teams, and most of the time they’re just a notch below average.
Golf: The problem with there being only one guy anyone cares about is…well, there’s only one guy everyone cares about. (That he has all the warmth and charm of a toxic waste dump certainly doesn’t help, either.) I actually had some interest when there were big names like Phil Mickelson and Vijay Singh to provide some competition.
Basketball/baseball: I can watch snippets at a time, but just too many delays and breaks and pauses for me to catch anywhere close to a full game. Besides that, the only story I find compelling right now is what the fallout will be if LeBron James gets a third ring. And I don’t find it THAT compelling.
Soccer: Yes, there’s the potential for excitement, but these moments are so few and far between that I can’t be bothered to catch a full game. Now, of course, the whole enterprise has become so nakedly corrupt that I can’t even take it seriously as a sport anymore. It just hasn’t been the same since France won the World Cup, has it? 
NASCAR: I tuned out for good when spectators started cheering Jeff Gordon wrecks. I’m bewildered that this received near-blanket tolerance (never mind the wink-wink-nudge-nudges on ESPN, which is usually good about calling out BS behavior). Haven’t seen much of a reason to return, especially with drivers now deliberately causing wrecks and somehow not receiving massive suspensions for it.
MMA: I actually liked the early years better (especially on DVD). It was so wild and free and fun, a good time had by all, and you never knew what to expect. Now, it’s almost like Olympic Greco-Roman wrestling, where the competitors are so evenly matched that its hard for anyone to stand out. (I understand that there are exceptions, but they’re largely confined to PPV, so I unfortunately haven’t seen much of them.) One thing I’d like to get my hands on is a nice, comprehensive CroCop retrospective. That man was a force of nature.
Olympics: The good news is that with the medal count issue finally put to bed, we’re free to focus on individuals, like we should have all along. The bad news is…the coverage still sucks. There’s just no getting around it. Honestly, I don’t mind beach volleyball or gymnastics or swimming, but do we need that much? How about judo, or fencing, or kayaking, or handball. Traditional disciplines are find, I’d just like more of them. And get those stupid yoo-ess-ay chants off my TV. I know where I am, dammit.
Poker: Not a sport. 
- The Nordictrack always put strain on my lower back for some reason. The first elliptical machine I had had a part snap while I was using it, and the other is making noise for some reason absolutely no one can explain. When it comes to exercise, simpler is definitely better.
** Did I mention pretty much zippo debate about how much the perfect regular season should enter the discussion? I believe I mentioned something like that. On this very website, no less.
