Grok walked a lot. Heck, he walked everywhere. Riding animals didn’t appear until after the agricultural revolution, so unless you buy into the ancient aliens theory, you accept that our paleolithic ancestors relied on self-ambulation to get around. It seems pretty plausible to suggest that we’re probably well-adapted to walking on a regular basis. I’d even go so far as to posit that walking might even be highly beneficial to our health and well-being. Given our extensive history with the activity, you might even say our genes “expect” us to walk.(This Mark's Daily Apple article was written by Mark Sisson, and is narrated by Brock Armstrong)
