Hey! Writer here again.

My character - a man in his mid-to-late twenties, needs an occupation. I'm trying to avoid the blind musician trope (though he is very musical as a hobby), and I'm looking for some suggestions on some career options for him.

I'm thinking somewhere in medical field, because it would be very useful to the plot. I just don't know what niche of medicine he would fit into the best.

This is an apocalyptic story, so anything that could be versatile and useful in an emergency situation would be awesome.

Any ideas?
