What kind of sports can I watch?
There are many sports you can watch like basketball, baseball, soccer, volleyball, football or rugby to name a few.  You will need to find which sport interests you the most.  If you ever played a sport in school or professionally then start by watching that sport to see if it still interests you.  If not, then start by watching any of these sports listed above for a couple hours and see if you are interested.  If not, then pick a different one and do the same thing until you find the sport that you really want to watch that holds your interest.
