Being a scout would be wonderful. Imagine running around in the forest all day (or night) and actually being useful att the same time! And I would be able to work alone and away from other people. My biggest problem against that is that I'm having knee problems and can't run at all at the moment, but hey, maybe that could change. Also I'm using glasses, but as long as I don't have to read at a long distance it should be fine, I have no trouble recognizing movement and position, it's just the details that gets blurred.
Night scout sounds best when I think about it, as I like to stay inside when it's too sunny.
But yeah, I have a lot against me at the scout front it seems. I could also work with crafts, if I happen to not me immune. I imagine handmade things are more in demand then than now.
If I can choose where I get born I'd say Finland or Norway. Sweden seems fine I wouldn't like living in ignorance of magic. Even if I was born in Sweden I'd probably begin to believe in it sooner or later anyway, as I tend to question things a lot and being open to all possibilities.
If I happened to become a mage I would put a lot of effort into mastering that I think. And just doing research about it in general. Maybe I would do research even if I wasn't a mage myself haha.
