From page 269:

Can't help but think that there's more to Mikkel than meets the eye, probably more than he'd like to show himself. I suppose farming doesn't require special education (as long as we speak about mundane job at least), but has he undergone any training to join army as a healer? And since he seems rather conversant with some things, how did he acquire that knowledge? While doing various jobs? Talking to educated fellows? Or maybe self-educating was his leisure? I am curious to find out eventually.

I agree that there's a lot more to the big fella than meets the eye. Hopefully Minna will provide more backstory some day.
Meanwhile, I like to think it helps that Mikkel grew up on the Madsen family farm, which we know they had long before the Rash. I picture it as the kind of big, rambling place where interesting old things lurk in the corners (kind of like "mathoms" in hobbit-holes).
So the Madsen kids could have grown up playing with beat-up old golf clubs, reading Before-Time magazines, maybe being allowed to look things up in Oldefar's medical encyclopedia (eeeww!!!). At any rate, they'd have more cultural continuity with Before Times than people who had to become refugees, gun-slinging wanderers, isolated survivalists, etc.

Mikkel's backstory is the one I am looking forward to most. I hope we get plenty of flashbacks. With his frequently changing jobs there's bound to be some story there. I'm picturing his young adult life less than happy. The longer it's not touched upon in canon the more tragic the backstory becomes in my imagination.

I think Mikkel is one of those jack-of-all-trades who knows little about a lot, because he was constantly doing different jobs. It makes you a creative problem solver and a quick thinker in many situations. About being a medic, maybe it is 'grannie knowledge' taught from generation to generation, if farms are far away from hospitals, you learn to fix wounds yourself with herbs and stuff?
