> For what it's worth, the median human is 31.1 years old. I wouldn't call something older than the median human "very recently, culturally."

That’s cute. Now try searching for the median age in developed countries, where people care enough to make up revisionist history about minor culture debates? (nevermind, I did it for you; it’s around 50)

More to the point, what’s the human lifespan in first-world countries? (average lifespan in the US is almost 80)

(All this is a tongue-in-cheek way of saying that perhaps disparaging people for being older than you is not such a bright idea. I know it’s hard to believe, but we’re not going anywhere for a while.)
