Horses are notoriously robust animals, hence the expression "healthy as a horse".
It's supposed to mean that you're healthy and such.
There really is no specific time you have to stop, but i'd say if you want healthy foals and a healthy horse after the fourth time.
Four legs. Horses have always had four legs.
I believe you mean MOUNTING a horse. Mounting a horse means to get on, you will end up sitting on the horse's back.
30 horse years unlike dogs, horses dont have their own years a horse can be aged by its teeth. in saying that, a 30 year old horse is in its later stages of life. so really 30 years in humans is 'lower middle age' so in horse terms, a fourteen year old horse would be 'middle age'

"To eat like a horse" means to eat a LOT of food.
A horse
The phrase "healthy as a horse" is believed to come from America and the UK in the 1860s. Horses were believed to be very powerful and energetic, meaning that it would be good to be as healthy and energetic as a horse.

Obviously healthy.
The reason a horse has to be healthy is because ... If you have a horse you probably want to ride it ,you cant if its ill . The vet bills are more expensive to a sick horse . You could go to court for animal cruelty if your horse has been neglected and end up with your horse being taken or a BIG fine.

The pulse rate of an adult horse at rest averages 30-40 beats per minute (bpm). A pulse rate of 50 or higher in an adult horse at rest may mean the horse is in physical distress.
How healthy a horse is is not based on the breed. It just depends on if it is taken care of. Some breeds seem unhealthy because each do have different configuration and needs. But really, it is the horse itself, not the breed itself. To keep a horse healthy use it for what it does. Like, some little pony can't be expected to gallop like a Thoroughbred. Give a horse a loving and fun place to live, and it will be healthy.
