Ah, makes sense. I think we (humans) have lost many skills and much knowledge as time as moved forward. We think we're so clever these days but I wonder if those that came before had a better, more intrinsic knowledge, of the world they lived in. I think they lived more in synergy with their surroundings. Little tricks like this one...Possibly a remnant from the past? I don't know, not that smart, but I surmise.

Thanks for replying. Much appreciated.
