on another note .... people who have lost limbs now have the brilliant technology you are talking about to replace them, hands that can move like real hands ..... artificial legs etc are improving all the time.... we couldn't live without technology .... however in an ideal world going back to the simpler style of living appeals to me, if only we could combine the two for the purpose of goodness .... and not ruin the planet in the process ... just my thoughts ...
