"Maybe you've already done some accidental selection on people who aren't injured too much by the chairs you currently have?  I did Google and find a lot of people talking about how much they hate this planet's chairs, but I have no idea how statistically common they are, because your planet does not spend an amount of money on chairs or chair research that is remotely proportional to the time that people spend in chairs.  Alternatively I cannot find any science research even though it exists, because your planet's systems for tagging funny pictures are two hundred times more sophisticated than anything your planet has ever tried with its science papers.  I am still not entirely sure that this is not the result of the moon driving you all insane, though Isabella has made steady progress on convincing me that it reflects a coherent general level of cognitive capacities and I have jumped ahead to update my second-order opinion over this predictable first-order trend."
