This knowledge has since been lo= st=20 and it is just in recent years (the last couple of hundred years) that we g= et=20 back this knowledge. Or perhaps a long time ago we knew it but didn't=20 understand it which is why we couldn't teach it to coming generations and f= or=20 every generation a little bit got lost.
