I've monitored this fourm for some time and appreciate all the information.  I have altered my EDC and made an urban PSK just based on the information here.  I had to register just to post to this thread and I suppose I'll get flamed for this stance but here it goes.
I have watched a couple of the Survivor series and learned a lot about a survival situation.  I realize that these people have medical personnel nearby should something go wrong and so forth.  These "Survivors" however must build some sort of shelter, build a fire, and are given very little food.  So to them there is an element of hardship.
Where I have learned a lot about a survival situation is the conflicts that arise between individuals.  You get the spoiled 20-something individual who has never learned to work and watch them [censored] unrelentlessly when asked to throw a branch on the fire.  This 20-something fails to realize that the 40-something guy has just spent 2 hours collecting the pile of firewood while they laid around gathering rays.  
It is also interesting to see how quickly the 40-something guy will cut loose the hot looking 20-something chick because she is such a load.  And to see the stupid choices they make under the artificially induced stress is worth it too.
In no way am I trying to imply that Survivor is real survival, but there are lessons to be learned.  Primarily that I'd rather be "lost" alone or with someone I know than with strangers.
