Any chance I can just do the full body scan and be done with it, and not have to do the agressive pat down with a knee replacement??? i would prefer it to the agressive pat down. As an elderly female senior, I greatly resent the full pat down even before recent changes the last few weeks. If I have a piece of metal in my knee from an operation, why the lift your arms and spread your legs and examine all over. THE METAL IS IN MY KNEE!!. There I vented, I feel better alrealy!!
