Im sorry to be anal, but technology has been around since the wheel.

and in the sixties I belive they had motor cars, phones, wireless, TV. penicillin xrays etc, you get where I;m going though.

In the fifties Child Birth was still a serious concern.

Recently my step daughter was told she had a degenerative eye disease and would be blind before she was 30.

however the doctors replaced her lens with an artificial one and replaaced her iris (I think).

A vaccine for small pox etc I could keep going on.

It is a direct result of technology which has allowed the species to be so succesfull.

sorry to ramble, peace all (and forgive my spelling)
