Football, nothing else comes close. I've played it, supported it, coached it. It is ingrained in our society and culture. We did invent it, we did bring it to other parts of the world. We are pretty crap at it though, for just now.
My favorite sport has to be football! Whether it's high school or college, I love watching and playing it. Plus, the atmosphere at the games is always electric. Check out https://zumroad.com/sport/ for some great info about the sport. I'm also a huge fan of basketball and soccer. I love playing pickup games with friends and watching the pros duke it out on the court or pitch. Basketball is especially great b/c it's fast-paced and requires a lot of agility, so it's fun to watch and play. Soccer's awesome too, and I appreciate the teamwork and skill involved.
There are many different sports in the world. They are different from each other, so there is plenty to choose from according to your individual taste and desire.In general, I love different games in which the ball participates. Whether it's basketball, volleyball or others. Ask why? The answer is simple, they are very interesting, mobile and exciting. And they are also team games, that is, the success of the game does not depend on one player, but on the participation of the entire team in it, that is, the team.
