Question 2

Answer 3

concept that the burden of lifetime illness might be compressed by medical intervention into a shorter period before death without necessarily increasing longevity

Question 4

Question 5

two approaches to maintain the existence of living things

Answer 5

immortality or reproduction

Question 6

Answer 6

negligible senescence

Question 7

Answer 7

programmed death by weismann

Question 8
