Parent is talking about mode, so the most common number. Let’s build a distribution that satisfy both. Oldest age is set 80, mode is set to 75. We start by distribution one percentage point to each age. Then add an extra to the mode and all the remaining to zero. We now have a distribution where the most common age of death, other than zero be in 70-80, and more than half the population die before they reach 40.
