I recall a popular discussion topic on the 'net which essentially goes like this: we take you, a XXI century human, and throw you back in time, say into medieval Europe. Are you going to survive? Prosper? What knowledge that you have will be useful to you? Will you be able to recreate useful things like antibiotics? Or will the local peasants just stone you to death for being too weird?
Let's recreate that thread, I have ideas. I would offer body building training for the kings soldiers because isolation exercises were not invented yet, for example. It may not be very useful but they would look impressive. I would sterilize surgical implements with boiling them, implement basic medical hygiene, challenge the miasma model, lots of stuff could be done.
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
