oooh forensics! if i were smart enough to do advanced maths easily and well advanced science, i would have probably opted for something like that. instead, i just read about people who do jobs like that - much more glamorous in books though i bet. why the shift from teaching English?
You don't really need to be scientific to do it...just very observant. But I suppose it depends on what sort of forensics you want to work with. As for the teaching, I just feel that I have so much more to learn and I can go back to teaching at any time. It's there for life now.
