I enjoy horseback riding(equestrianism)!  Do you ride?
1_Wizard
I used to ride! I still own horses, but I've trained them for practical working purposes now. They pull farm equipment for me.

Really!  That's practical.  Are they horses specifically bred for that purpose?
1_Wizard
The ones I own are not, but I've worked with breeds like the Percheron that are bred to be "in harness".

Interesting!  How much do these horses weigh?
1_Wizard
Percherons were originally used as war horses, so they can weigh upwards of a ton. They had to be so big to carry knights in all their armor - which could weigh more than 400 lbs.

Fascinating!  So I guess they were the first "tank"!

You could say that! I also love watching horse sports like in the Olymics. Dressage and show jumping are some of my favorites to watch.
