>That's not true unless HN readers are a representative sample of the overall 25-44 population, which they aren't. Higher-income/SES is associated with a lower mortality rate than the overall population average.

7K/year is for the healthy, affluent, tech-worker-heavy population already. For the general population, US, is ~ 12K/year.

Not that higher-income/SES is necessarily representative in a supposed 5m strong HN readership - it would be all kinds, from all around the world. SV startup / FAANG types are just a small slice.
