Answer to Question 1

The short answer is no. Mortality rates are a good way to judge how healthy people were and are.Most people today live longer than their ancestors.This translates to Americans being healthier today than in the past.

Answer to Question 2

Scientists have reached the frontier of genetic engineering. We are about to cross over.Some worms have had their life spans extended by six times through manipulating genes.Eventually, might this not be possible for people?Spare body parts may be able to be grown from stem cells to replace theparts that wear out.Nanorobots may roam our bodies, constantly repairing cell damage and keeping us young.Greatly extended life spans may permit the good health and creative aging of many of today's elderly to continue over many, many years.
