Hi HN, author here. Glad you're enjoying it!

I put it together as a kind of Stoic practice to reflect on the fact that we will all die, but also with a data scientist hat on to try to get myself to think about life expectancy as a distribution, rather than an exact number.

Silly question: If I read this correctly, your chances of death go down after ~80 years of age. Why is this? Is it because most things that will get you would have earlier or just that the population size is so low at that extreme?

It's your probability of dying at those ages. The higher ages have lower probability because most people will have already died. In other words, the probability of dying at the age of 80 is conditional on the probability of surviving to the age of 80.

Exactly this. What's plotted is the chance of surviving to that age then dying.

Thanks.
