Had a tooth pulled this morning. I’m writing on book on growth and markets—part it deals with how much life has changed in the last 100 years. Dentistry is an interesting example. Lidocaine beats a swig from a whiskey bottle, though the whiskey would be better today than it was then. The antibiotics prevent some gruesome infection from forming. The Tylenol with codeine that I may be turning to in a few hours is better than finishing the whiskey bottle. Then again, some things don’t change much. Basically there’s something that’s way too much like a pair of pliers and some physical exertion is required on the part of the extractor.
