I also like the Mafia Wars and World of Warcraft!
I used to play almost everyday during those days when I was really hooked into playing them. But, I'm too busy to play right now. I miss playing those games!
I exercise for about three to four times a week.
Basically, I do a lot jogging and running.
Then, I play sports as well, which is tennis.
I do not take any supplements, just pure exercising and healthy eating.
And.. lots of water! :)
