For example, Rowe tells us about a pig farmer in the United States, who managed to amass a fortune ever since he started transporting and feeding his pigs the leftovers from restaurants in Las Vegas. The farmer knew that the discarded food was rich in protein. When the pigs ate the protein rich meal they would grow faster and bigger which meant a bigger turnover. The farmer jokes of how he turned down an offer of $60 million for his farm recently. Who would have thought there was so much money in pig farming?! Did you?
