I read an op-ed piece some years ago in which the author was in favor of a mandatory two year service commitment in the armed forces. His premise was that many, if not most, today have never been cold, hot , hungry, wet, etc. and therefore are unable to adequately manage a little discomfort.
He contended that if young people were forced to manage discomfort and shut up about it, the wussification of America would not be occurring.
I think he makes an excellent point there.
