Personally, I grew up in a medical environment. Three relatives were volunteers at hospitals. Then they were part of the V.O.N. (Voluntary Order of Nurses) and the St John's Ambulance service.
Maternal grandmother was a graduated chemist in mixing powders at the local Chemistry shop (aka now known as Pharmacies), she also spoke Latin fluently. Sibling was studying Biochemistry at specialist college.
Papa got me interested in reading the whole 3 collections of medical encyclopaedia we had at home, plus helping sibling he would get me to read her books as well.
Honestly, I would have gone for medical secretary certificate as medical schools were out of costs. Didn't get to do that as residency was required to attend medical secretary school. No one wanted to move to that city, so my dreams went up in flames.
However, if I'd had the money, I wanted to do A&E (Accident and Emergency in UK) or Emergency Room (ER in North America).
Long story sorry, but that is what draws me to the TV medical series. At the end of the day, helping people at the most urgent time...
