Probably both, equally. I turn everything in our house into a competition and I HATE to lose, but you know what...I really LOVE to win!
I'm getting older, so I'm not going to compete with the younger guys on a field/court anymore, but I'm still competing in other areas. At home playing the family in board games, cards, ping-pong, free throw shooting contest in the driveway, Wii games, etc...I want to Win.
My wife and I bought the DVD series of '24' last year. At each commercial break the clock for '24' is ticking at a certain time to let you know where they're at on the day/night in the series. We'd have a contest to see who could come closer to the time on the '24' clock after the commercial breaks...I owned her!
My family went to a ball game last Friday night, and it was pretty cold. Before jumping in the vehicle after the game, our family bets on what the temperature will read after five minutes on the road...it's pretty funny! We'll also bet on how long it will take to get home, I love that one, since I'm the driver!
