I just told a friend I could not drive with her to NC to visit another friend...it's two days in the car. She did not understand, and kept telling me I could 'lay down in the back seat' blah, blah, blah. My legs fall asleep and my back aches within minutes of being seated in a car. One of our cars has heated seats and that's the one I take if I have to travel any distance. Even the seat belt hurts. Air conditioning blowing on my face hurts. Not many people 'get it.'
