I feel your angst! As we survive the aging process, certain things happen! These things are rarely enjoyable -- see bladder failure, neurological issues, hard impacts with objects such as floors, brick hearths, roadways, etc. And then there are the rides in the back of the ambulance while strapped to a long board wearing a neck collar to immobilize your c-spine! X-rays are not bad and neither are CT scans nor ultrasounds! MRIs however are debilitating and horrendous (unless they do them while you are unconscious). However, as long as you/we can write about them, we are alive and moving forward! Keep on smiling!
