Which two end points are most commonly used for years of potential life lost?

1. Years of potential life lost sums the gap between an end point and each age at death below it. 2. The two end points in common use are age 65 years and average life expectancy. 3. Using 65 counts only the deaths below that age, which is fewer than 30% of all deaths. 4. Using remaining life expectancy draws on deaths at every age, so it behaves more like a crude mortality rate. _Source: CDC Principles of Epidemiology in Public Health Practice (3rd ed., US federal, public domain), Lesson 3 "Measures of Risk", section Definition of years of potential life lost_
