And if you don't already to this, start doing some mild yoga exercises. Great stress reliever, and it's a wonderful low stress way to 'warm up' in the morning.

I got a beginner's yoga videotape on the recommendation of my physical therapist after my back surgery, and I memorized the exercises quickly. Most of the beginner exercises are easily modified to whatever your knee will let you do.

Take care and keep singing, Áine
