Was a non-pro but very serious ballet dancer for years before getting fibromyalgia and having to quit. Running was a total no-no in the ballet studio--its effect on leg muscles not compatible with ballet needs, not to mention injury potential/joint stress.
"My predominant feeling is one of gratitude. I have loved and been loved;I have been given much and I have given something in return...Above all, I have been a sentient being, a thinking animal, on this beautiful planet, and that in itself has been an enormous privilege and an adventure." O. Sacks
