How long would you wait...

Depends how good the doctor is. Your time is valuable, but your life and well-being transcend your importance.
It has absolutely nothing to do with importance! At my age you realize you are looking down the short end of the tunnel. The reaper is waiting and we have no vote. Tell me the truth and keep your word and we will get along fine. They call the bottom graduate in every medical class Doctor,but they are fallible humans and are there to help us. Not the other way around!
