Favourite sports to partake in would be Paddling, Rugby, and Football (soccer for the yanks )
Favourite sport to watch has to be F1. Miss the sound of the V8's, likewise during the V8's, missed the sound of the V10's
Has to be said, totally invested in this years championship as my lineup for our F1 comp is currently winning (no one cares about 33x >_>)
NFL Football would be my favorite and most watched. I don't miss any Philadelphia Eagles games!
NHL Hockey is probably my 2nd favorite but I don't watch regularly or follow it unless we're having a really good season and approaching the playoffs.
Baseball, Nascar, and WWE wrestling are all in third place because I occasionally watch them but not on a regular basis. The last season of baseball I really watched was when the Phillies won the World Series in 2008.
I used to be into NBA basketball in the 90s and early 2000s but in recent years I've completely lost interest.
I'm not sure if it counts but I also enjoy watching the Olympics, particularly the summer over the winter, but not every single event.
Volleyball, Football, Soccer, Poker (if that counts), Poke her (you bet that counts :lol
For me, probably a tie between boxing and football. I've personally competed in both, and watched both for a long time. I just love the visceral nature of boxing, and its purity, but I love the complicated stuff of football as well. I can't live without either.
