I am an ardent lover of knowledge. As a scientist, it is my pleasant hobby to discover the hidden virtues in plants, for the upkeep of animals and man. This chiefly revolves around God, the unnegotiable Creator of heaven and earth. The academic world tickles my fancy a whole lot. Therefore, as long as I have this life, I will keep on reading, studying, researching and writing, while encouraging the young ones to love knowledge and it's application, to solving life's numerous challenges.
