Im a really good horse trainer, its variety of practices that teach horses to perform certain behaviors
Interesting I dont know much about horses but I have rode them a few times.
They are trained to be manageable by humans for everyday care, and also for riding and other things
What other things are horses good for besides riding?
Strangest thing for me is therapeutic horseback riding for people with disabilities it actually helps the people i have seen it!
Wow thats really cool! I had no idea horses did things like that
Yes, there is tremendous controversy over various methods of horse training, but people have did it for centuries now so i think its a part of culture 
Yeah I live close to a track that races horses. I have been a few times its really fun!
Do you bet on them? Horse domestication has been around since 3500BC
I have never bet on them I just like to watch them.
