Using evidence from the book, describe Morrie Schwartz physical and personality charateristics when Mitch first knew him?

From the text:

He is a small man who takes small steps, as if a strong wind could, at any time, whisk him up into the clouds. In his graduation day robe, he looks like a cross between a biblical prophet and a Christmas elf He has sparkling blue green eyes, thinning silver hair that spills onto his forehead, big ears, a triangular nose, and tufts of graying eyebrows. Although his teeth are crooked and his lower ones are slanted back—as if someone had once punched them in—when he smiles it’s as if you’d just told him the first joke on earth.
