I have an oddball but serious question. A friend of mine has a big brother who's a doc. My friend's mom said that the US medical residency system was started by a guy who was on cocaine. She said that he could stay up for three days straight (thanks to the cocaine) and so he thought that everyone else could too - and that's where the long hours in residency come from. Is there any truth to this? I tried Google but was unable to find anything.
