Exam 2: Why Do Our Bodies Grow Old

According to Mor, the compression of morbidity hypothesis is now generally accepted as valid.

Do you agree or disagree with de Grey that developing therapies that would dramatically increase life expectancy is tantamount to "playing God"?

Olshansky agrees with de Grey ("We will be able to live to 1,000") that with sufficient resources devoted to research, we can find a cure for aging.

Research in the area of cryobiology has found that raising and maintaining a higher body temperature can increase the life span in fruit flies and some vertebrates.

According to Fries and Crapo, average life expectancy has increased while life span has remained the same.

Compare and contrast de Grey's "We Will Be Able to Live to 1,000" and Olshansky's views on the likelihood of preventing and curing aging. What evidence does Olshansky use to refute de Grey's argument?
