I think horses are some of the coolest animals in the world
Horses are one of my favorite animals. They've evolved over the past 45 million years from having multiple toes to one hoof! 
Wow I have no idea!
They have a pretty neat history. Animals with an odd number of toes, like horses, are called perissodactyl. Other animals in this group are rhinos and tapirs. 
I have always wanted to see a horse get its shoes put on.
I've seen it many, many times. It's a really neat process. The person who does it is called a farrier. 
How long does horses live normally.
With good care and attention from humans, they can live well into their upper 20s, early 30s, and even beyond. Small ponies seem to live longer than larger horses in my experience.
