This is a time when people were still sealing wounds with boiling oil.
So yes, even if you have no formal first aid training you can be a great healer.
I'd say we have a better shot at living a longer period of time (over a year) since we could take basic precautions against disease and germs. The Middle Ages guy/gal would probably die of our modern germs within a few days (similar to the Indians when they met European explorers).
Let's flip this around a bit. Who would have a better chance of survival, one of us transported back to the Middle Ages, or a person in the Middle Ages transported to 2009? I'd say we have a better shot at living a longer period of time (over a year) since we could take basic precautions against disease and germs.

Earlier quoted context omitted.
Almost certainly not more efficient, but growing plants can't use oil directly, and since we can supply enormous amounts of external energy by the standards of a crop plant, engineering them to be able to use it more effectively is useful even if the plant itself is less efficient overall.
Almost any sort of mechanical or chemical process is more efficient than plants. Photosynthesis is only 3% efficient; by the time the energy enters the plant, you've lost 97% of it. Then you figure various biological pathways, and you're down to maybe 1-2% efficiency for the best plants. This, among other reasons, is why grain ethanol was such a scam. The worst mechanical processes, by contrast, usually get at least…
The primary [photosynthetic] reactions have close to 100% quantum efficiency (i.e., one quantum of light leads to one electron transfer); and under most ideal conditions, the overall energy efficiency can reach 35%. Due to losses at all steps in biochemistry, one has been able to get only about 1 to 2% energy efficiency in most crop plants. Sugarcane is an exception as it can have almost 8% efficiency.
