Document Summary
Biological aging theories and longevity - week two. Living long and well: life span is used to define the theoretical limit on the length of life, given ideal conditions (does not vary by culture/nation - fixed for human species). For humans, assumed to be 115-120 years for centuries. Life expectancy: the number of years a person can expect to live, highly variable. Depends on year of birth, age, gender, race, health behaviours (smoking, etc), and culture. Can be calculated for any age, however dramatically increased over last 100 yrs due to improved public health (sanitation, vaccination, & increased infant survival). Jeanne-louise calment (french) held world record 122 years old, died in 1997. In the early 20th century, large difference in l. e. b/t different ethnicities than now. Women have a longer l. e, than men in almost all countries. Nobody escapes mortality (death), but we all hope to escape morbidity (illness).
