I never wanted to be a doctor when I “grew up” (I get squeamish around wounds), but when I was a kid, I did love to play with those play-doctor kits. You know, the ones with the black plastic bag and the plastic bandaids inside? My favorite parts were the little plastic arm-cuff bandages and the stethoscopes. Heck, I still like to play with stethoscopes when I can get my hands on them!
