Wikipedia says that they “lack short wavelength sensitive visual pigments in their cone cells”, so they don’t see blue as well as we do… Which isn’t surprising really.

They could stack rocks to create a mosaic.

Just like the Philadelphia mass turbulence of 1947.

Thank you for sharing.

Those times when I’ve achieved runners high it was when I pushed myself to carry a heavier load, and walk faster. Never during endurance training.

I would feel my legs burn and there’s a temptation to slow down, but that was the signal to forge on commit to walking faster.

At the time I had a very specific motivation for walking, and I wish I hadn’t stopped walking when that motivation was gone. It’s hard to start up again.
