Why geese don't get obese (and we do)

Sinopse

"What drives us to eat and accounts for different appetites? Why is breathing at high altitudes easy for birds and difficult for humans? Why do animals have two sets of sensory organs--eyes, ears, nostrils, etc ...?" "In Why Geese Don't Get Obese, physiologist Eric Widmaier describes the astonishing ways humans and other creatures have adapted to their environmental challenges in order to survive. Surprising exampies, a sense of humor, and some insightful science make this book a delightful and lively read. Book jacket."--Jacket.
