Oh...that I did not know, I just thought skii ...it is not that simple.No downhill skiing here. You need good knees for that. I've been thinking about getting cross country skis though
As my chiro was adjusting my hips and back yesterday he asked me did you do much movement? I told him I walk up and down the stair so many times a day because of my screaming chickens, movement is not an issue here, those cakes are!! He was lost for words.
