I had a helper one year, a gray headed gent that looked to be about 55-60 years old. When I saw him I thought to myself, no way. Well, this guy worked circles around the younger folks. After working with him and talking to him for a while I found out: He was an executive with southern pacific railroad. He was about to retire. He lived in a subdivision I didn't deliver to but was familiar with. The homes there start at about $500,000.00, and this was 30 years ago. Our division manager lived in the same subdivision. He took off a month of vacation and did this job every year. He basically said he did it to keep in shape and the money he made went to gifts for Christmas. The guy never complained and had a good attitude throughout.
