Having total knee replacements means that while I can hike up all day long I cant hike downhill without my knees swelling up. But strap skis on my legs and I can get down the mountain! One of my favorite things to do on the planet is to climb and ski mountains. When conditions are good, the feeling lasts for years... My ski pals started yelling old guys rockin'! After our runs - and it kind of stuck. Arguably we are not that old, but we are definitely not young. We are still rockin' it! #oldguysrockin!
