In the News (From Nature.com): “Schooling fish take up different positions in the group according to their aerobic abilities. …When schools were swimming at high speed, fish less able to supply oxygen to their muscles ended up at the back, where they could reduce their workload. By contrast, fish with higher aerobic capacity that were better able to withstand drag forces took up positions at the front. Having fitter fish in the lead could allow schools to maximize their swimming speed.”
My Comment: In nature, everything is arranged according to the principle of mutual guarantee. Kabbalah urges us to connect in this way, and numerous articles indicate that mutual guarantee is the basis of interaction in a group and society, exactly like in the case of the fish!
