alt Hacker News>Whatever, set the clock to the 1820s. Or the 1400s. Or the 1200s. Or the 1990's or 200 BCE, I don't care.
I think they may have taken your prompt and thought about the 1820s, 1400s, 1200s or 200 BCE. Did you mean to direct people to discuss the 1990s by listing the other 4 eras?
I mean to say Homo sapiens has existed for 300,000 years. They have not been 70%+ overweight or obese for most of those years. All the way until the 90s, obesity rates have been WAY lower, even in food-abundant societies.
