Modern medical advances might mean people could live 200 years. In 2009, the life expectancy is about 80 years. Assume that, due to modern advances, life expectancy gains 5.5 years every decade. From 2009, in how many years would humanity achieve a life expectancy of 130 years? Humanity would achieve a life expectancy of 130 years in approximately nothing years. (Round up to the nearest year.)

Life Expectancy Some scientists believe there is a limit to how long humans can live. One supporting argument is that during the past century, life expectancy from age 65 has increased more slowly than life expectancy from birth, so eventually these two will be equal, at which point, according to these scientists, life expectancy should increase no further. In $1900,$ life expectancy at birth was 46 yr, and life expectancy at age 65 was 76 yr. In 2010 , these figures had risen to 78.7 and $84.1,$ respectively. In both cases, the increase in life expectancy has been linear. Using these assumptions and the data given, find the maximum life expectancy for humans. Source: Science.

Advances in medical science and healthier lifestyles have resulted in longer life expectancies. The life expectancy of a male whose current age is $x$ years old is $$\begin{array}{ll}f(x)=0.0069502 x^{2}-1.6357 x+93.76 & (60 \leq x \leq 75)\end{array}$$ years. What is the life expectancy of a male whose current age is $65 ?$ A male whose current age is $75 ?$
