Today is Sunday. It's the day of the Super Bowl LI which is considered as the Spring Festival Gala of the United States.

I like watching American football game rather than rugby football game. I think the former is more technical. I know the rules of American football but I know few knowledge of NFL (the National Football League). So I support neither of the two teams. And the Super Bowl game always play in a Monday's morning, so I have never watched a live game. It really declines my interest in the game.

As we know, American's big four sports are football, basketball, baseball and ice hockey. Those games are really exciting and amazing. People can gain strength and feel joy by watching those games. NFL, NBA, MLB and NHL are the most successful professional sports organizations in the world. We have to admire the American people's love to the sports and their business capability.
