"A study by the Centers for Disease Control and Prevention reported that Black males' life expectancy has increased by 1.2 years to 67.3 years. For Black females it increased by half a year to 74.7 years.
For White males and females the numbers were, respectively, 74.3 years and 79.3 years."
So we will be dead before we stop working.
A more appropriate statistic for this purpose, though, is what is the life expectancy of someone who is currently 50 (or 40?). I don't have exact numbers in front of me, but every year a person lives makes their actuarial life expectancy just a little longer.
