I ended up at a teaching hospital once. They saved my life so I wasn't to awful critical of being on display. They saw me as a miracle so I was sorta flattered that I was so popular.
I was on 3 a day visits and they'd all been filled in already as to what I'd endured. They all had theories they wanted input on so I answered alot of questions. 
I had scar revision surgery on my arm, at Duke, by a nationally recognized plastic surgeon.
The plastic surgeon said ....."hey I can make this look great! I'll cut here, and here, and here, and restitch it and it will look terrific.....you'll have just a fine line that will eventially disappear"
"ok"...said I....."make it look great". After all, I wasn't having to pay for it. Insurance was paying for most of it,and the urology dept was picking up the difference, and the surgeon was comping his fee.
He took lots of pictures ....after all, my scars from 2 skin graftings were going basically all going to disappear after he applied his wonderful skill with scapel, needle and thread.
He cut and stitched for several hours. I was kind of awake for it....and he couldn't get my arm completely numb.
All those pictures he took?
He added several sets to them.
Everytime he injected the incisions with steroids to reduce the inflamation.
He used them at many lectures all over the world....."Never tell a patient that you
KNOW you can make it better....."
31 years ago.....
.....that was the last time I let anyone near my arm with a sharp instrument.....of any kind.
