Its interesting visiting a doctor, being asked your profession, and replying engineer. Usually, their faces light up. Here's someone with a STEM education and an analytical mind. They can have a meaningful conversation about what's wrong, and what can be done about it. This is clearly not the kind of interaction they have with most patients, and most medical people seem to appreciate the opportunity.
Happens to me a lot. Once you tell them you want to know every detail, and also when you ask really obscure technical questions, they really light up.
I'm the nerd that brings my thermal camera to the doctor
In fact if a doctor or whoever it is, could be a tradie for example, doesn't light up and start talking technical when you ask, that's someone whos incompetant and should be avoided IMO.
