Yes, magic. It’s a wondrous process that has more positives than negatives. Middle age and beyond is not something most species get to live through. New ideas suggest that this vital later phase of life is precisely why human beings have ended up taking over the planet! If you are over 50, pat yourself on the back, for being Nature’s most highly evolved organism. Biologically and socially, you are streets ahead of the youngsters who hog today’s limelight! But why did evolution take us down that path? The answer is inextricably bound up with the exceptional nature of humans. We are a brilliantly adaptive species, for which the process of learning has been crucial. Today we can read books and Google information. But before the advent of writing, much less computers, skills had to be learned and it took time; decades in fact. Oftentimes, the necessary skills were not accumulated till after the age of 40. Surviving long enough to acquire these skills would be a strong evolutionary advantage, which would be selected for by Nature. These skills would be passed on to other members of the tribe and that would give them the advantage over competitors, whether the human kind of the sabre-toothed kind! We would quickly “develop” a middle age, even if we didn’t start with one. Middle age would be a valuable commodity that Nature chose for us!
