Horse years/Human years

I've never really taken the time to look up how human and horse years compare.  Most of us know that every human year = 7 dogs years, so that's pretty easy to compute.  I found this information about horse to human age comparison:

First horse year = 12 human years
Second horse year = 7 human years
Next three horse years = 4 human years each
Subsequent years = 2 1/2 human years each

Sassy is 12 years old, so that makes her 48.5 in human years.

Our big boy Chini, who just turned 5, is 31 in human years (that's Phoenix in the background)

My baby Piper, who just turned 4 years old, is already 27 in human years (she's growing up so fast...sniff, sniff...)

I couldn't resist putting in a pic of her as a little girl, not quite a year old, when I first brought her home:

Phoenix is a young 34 years old, so that actually makes him 103.5 years old! I can only hope I age as well as he has.

Of course, even though horses age much faster than humans, they also age better. And it also depends on a lot of factors such as their genetics, size and lifestyle. Phoenix is such a spoiled old guy, I'm sure he will live to see 40. Just imagine --118.5 in human years!
