A walk is just as good…
When the spirits are low, when the day appears dark, when work becomes monotonous, when hope hardly seems worth having,
just mount a bicycle and go out for a spin down the road,
without a thought on anything but on the ride you are taking.
Sir Arthur Conan Doyle, Scientific American, 1896
[or as I saw it written on a wall in Italy…”pedala senza pensare a nient’altro che alla strada che percorri”]
