Years ago I worked with an old fellow,anything I needed to know I would have no hesitation in asking him,he seemed to have an answer to anything,not in a patronising or big headed way,but in a genuine and giving way,it was just his nature,shared many a pint with him,but anyway we were talking one day about human diseases and he said you know there is a cure somewhere in nature for all of mans ailments,he said they haven't found them all yet but they will.He wasn't well read or academic in any way,but to me he was a wise old bird,and a good mate
