I had the opportunity to see a special presentation with my dad by Nando Parrado, or better known by most of you as the Scrum half and captain of the Uruguayan rugby team that was stranded in the Andes mountains, very very far from civilization.
it was also the same chilling story that was made into a very popular hollywood movie I'm sure you all know, "ALIVE"
he wrote an excellent book and made an excellent presentation, and really dealt with alot of the moral and ethical issues one would encounter being in their position. (just in case you didnt know or werent sure, yes, they did eat the flesh of their other[already dead] teammates.)
