Needs? I guess that is what bothers so many folks. They keep expanding their needs until they are dependent on too many things and too many other people... I wonder how many things in the average American home could be eliminated if the question were asked, "Must I really have this?" I guess most of the extras are chalked up to comfort or saving time. Funny thing about comfort - one man's comfort is another man's misery. Most people do't work hard enough physically anymore, and comfort is not easy to find. It is surprising how comfortable a hard bunk can be after you come down off a mountain.
