Am in my late 30’s and I don’t know nor did I ever know. As a result I consider that a crummy ice-breaker.
scratch that. I once wanted to be an electrical engineer but I didn’t know that’s what it was called so I said I wanted to be “an electrician” which I have zero interest in. -You would not believe the number of times people have recommended “electrician” to me as a career choice. Also, I don’t have the aptitude to complete the advanced math and advanced science courses that are required to get an EE degree. That’s not for lack of repeated tries, either. Some things just aren’t meant to be.
