It is of course: Are we Humans naturally knuckle-walkers or fist/palm walkers? Clearly we were never designed to walk around on two feet. Whatever way you look at it, there's no escaping the fact that walking on all-fours is a more robust, faster, healthier and much more efficient means in all ways of getting around. If you don't find that, it's because you've been trained into a life of bipedalism... some of which may have malformed you permanently and you may never recover from properly. It's also confounded by the fact that my knuckles and fists have worn away and broken off, probably coincidentally after I started walking on all fours (or due to earlier malformation).
As paleos we must of course throw off the fashionable, artificial, vain, unnatural, modern, anomaly of bipedalism and use our four limbs to get around and climb up trees. In fact right now I am suspended upside down from just my legs, aaahhh the refreshing feeling of blood rushing to my head and clotting there is truly magnificent.
Anyway, here's the article:
