Based on current life expectancy data, to what age is the average 80-year-old expected to live?

Life in This Century. Example 5 assumed that the life expectancy between 2000 and 2100 would increase by the same absolute amount as it did between 1900 and 2000. For women, life expectancy in the 20th century increased 32 years, and for men, it increased 28 years. For Exercises 29 and 30, suppose instead that life expectancy between 2000 and 2100 increases by the same percentage as it did between 1900 and 2000.
