* How badly affected is he likely to be by that kind of exposure? Assuming the unconsciousness hasn't done him any damage, would there be any trouble reviving him, and how much difficulty would he have with walking a shortish distance to get to the nearest house for assistance?
* If he was then taken to a hospital, what kind of treatment/examination would he receive there, and how long would they probably keep hold of him?
* What kind of aftereffects, if any, might he be suffering over the next few days?
Any kind of information would be appreciated.
