  acshually depends if you’re walking against or with the spin of the earth but whatever

    Apparently the average radius of the Earth at its equator is 6,378,000m. This means that in a day, someone sitting on a couch at the equator would travel (2 * \pi * 6378,000)m, which equals 40053840m. There are around 86,400 seconds in a day, so the equatorial couch sitter travels at 464m/s (rounded to 3s.f). That’s 1040mph.

    I think the average walking speed is 3pmh. Amusingly, the mph figure I calculated above is 1037 if rounded to 4s.f. rather than 3, so the speed difference between the walker and a couch sitter is literally a rounding error.

    The conclusion here is something that everyone here already knew before I wrote this comment: it’s hard to make any sense of individual human health progress if we try to think of it on a planetary scale.

      The mix of standard and weird US units hurts my head.

  Not me, I can roll across my couch at lightning speed.
