I like athletics. I am into running and tennis. What about you?
Those are some impressive Athletic sports  you do. I Trail Running, Football, Rugy, Surfing, Mtn Biking and Kite Boarding. 
Whoa you are all over the map with your athletics. I was watching rugby today. Very interesting sport.
I also compete in the Highland Games. You should youtube Rugby league football in Australia. They play rougher then American's play football. 
Yeah I can't believe they don't wear helmets. Is there a lot of concussions?
Yes, but most keep playing. It's not like American Football where Concussions and other types of repetitive play-related head blows will force you into retirement. 
I will look up the Australian rugby. Now I need to learn all the rules of rugby, haha.
Australian rugby has 128.5 million viewers worldwide that's 4 times more then the NFL.
