Did You Know?
Even with all that scheduled treadmill time, astronauts still lose bone density in space. The impact forces from walking in microgravity are measurably lower than walking on Earth, which seems to be part of why exercise alone doesn't fully offset the loss.
One of the earliest known odometers, described by the Roman architect Vitruvius, was a gear-driven device mounted on a chariot wheel that dropped a pebble into a box every time it completed one mile, a mechanical ancestor of the step counter on your phone.
