fountain of youth

what is the fountain of youth. Is it a place, or an object? i think its the water in the fountain of youth that is the real secret. Is it possible that drinking adequte amounts of water will help you live longer? I think so, i also think its very popssible that the fountain of youth is a metaphor for water. just plain and simple water, wich is why the fountain of youth has never been found. WHY? water is good for us as we know, when we grow old we prune up ...almost like being dehydrated. whats the cure for hydration? water...thus old age (dehydration of the body) can be reversed(slow down old age) with the fountain of youth (water)
