Basic care, size, genetics and health affect how a horse ages. The growth and aging occurs much faster in a horse than it does in a human.
He would be around 20 years old.

A two year old wolf, in human years, is two years old.
A 21 year old cat is about 101 years old in human years.
Here is an article from EQUUS magazine August 2006 Comparatively Speaking: Although there's no simple equation for calculating how old your horse is in human years, it's possible to come up with a ballpark figure: *First horse year = 12 human years *Second horse year = 7 human years *Next three horse years = 4 years each *Subsequent horse years = 2 1/2 years each. This puts a 2-year-old colt in his late teens, a 5-year-old at full maturity and a 15-year-old at late middle age. What accounts for the difference in aging? Largely genetics and lifestyle. Horses mature much more quickly than their owners, so their formative years add up exponentially. Horses experience a few days of infancy, a few months of childhood and a year or more as teens. They are fully mature by 4 or 5 years of age, when they enter a lengthy active adulthood. Then they experience a short decline and brief terminal illness.
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'
Dogs age at 7 years compared to one human year... thus your 12 year old dog would be 84 years old in human years
Contrary to the old saying one dog year is not equivalent to seven human years. Vets use the formula that a one-year-old dog is 21 in human years, and every year of the dog's life thereafter is like 4 human years. So your two-year-old dog is 25 in human terms.
the fly is about 179 in human years
