You had to have extracurricular activities to list on your college application since forever, and among other things, I attended Medical Club. I guess it attracted would be doctors, which was me in my parents' eye but I always wanted to be an engineer.
It was a fantastic experience on account of practicing medical doctors in specialized fields taking time out of their busy schedules to give an after-school talk to would be doctors. I vividly remember the Scared Straight lecture on VD that was accompanied with slides of male and female pudenda wracked with syphilitic sores, but somehow I think this was wasted on the type of earnest student attending Medical Club who was an ambitious grind with head down in the books instead of taking time to catch those diseases.
The other talk I remember was of a doctor who was in on the early use of coronary bypass surgery--this was in the early 1970s. What ran counter to all of the received wisdom on smoking was him saying, "Everyone talks about smoking will give you lung cancer, but that is not a certainty. What people don't tell you about cigarettes is that it is a certainty that you will get cardiovascular disease."
Oh, and the talk had many graphic slides of the lungs of dead cigarette smokers.
Think of it, President Eisenhower had his heart attacks and that is where we got the thing that we should be eating seed oils instead of animal fats and butter. But what no one talk about was Ike, at least in his war years, was a heavy smoker.
Mind you, Robert Noyce of the Fairchild Planar Process fame, the invention that to this day powers the microelectronics revolution, died in his early 60's of a heart attack. Sure shootin', his Wikipedia page mentions him to be a heavy smoker.
