I was asked to give a talk with this title several years ago for the annual meeting of the American College of Surgeons. I was surprised at the enthusiastic response then, and more surprised at how many times other folks have asked me to talk about this topic since. I had a friend recently ask me if there was a link to the talk that they could share with others. It wasn’t recorded (that I know of), so I’m posting the slides here. I think they are mostly self explanatory, but if you have any questions, please let me know!
