Helm's Deep Query

Very interesting comments regarding Elves. Never really looked at it in that way before. Still, taking the thought further and expanding, does that mean that all non human races are of such ilk, in their own unique ways, and it is only men who move toward the future. If it does its a neat way of arriving at why there are no elves et al around today. Or am I now mixing reality with fantasy...... and if so, is that a bad thing?
