I don't feel my age and I usually don't act it, either. I think that is part of the secret! (How is a 40-something cowgirl supposed to act anyway?)
The other day I had the 2 old guy horses out roaming around while I was outside doing chores. Phoenix came up to the fence panels and I didn't even think about it, just climbed up and jumped on his back. He took me for a little ride -- no reins, no saddle -- just a handful of mane. And I lived to tell about it...ha ha.
And when I'm 60, I hope I'll be doing the same!
