So my DNA is in good shape, but my knees are shot.
30 minutes a day total on the stationary bike, elliptical and stairmaster.
No knee pounding.
Nice to know I'm not alone. Bone on bone with an arthritic cyst in each knee. Fortunately cortisone shots do help. I'm hoping I die before I need knee replacements. Must have been the cheerleading, and fancy jumps that I did in my youth.
