You're kidding, right? The FB engineers are probably mostly under 30 - you're assuming they'll die before they're 80?
Added in edit: Well, I guess from the downvote(s) that people do assume the FB engineers will die before they're 80.
Added in further edit: It's been suggested that my comment lowered the tone. If that's the case then I apologize, it wasn't intended to. It's been further pointed out that from 27 years of age onwards, the male life expectancy in the USA is indeed 50 years or less. So I was wrong anyway. I've learned something, for which I am not sorry. I was wrong, for which I am not sorry, because it afforded me the opportunity to learn. I may have lowered the tone, for which I am sorry.
