Michael Phelps in 67 years?

I love coming across individuals who have figured out how to age successfully, whether I know them personally or learn about them in some other way.

Adolph "Sonny Boy" Kiefer is most likely the swimming legend you never heard of. A gold-medal winner in the 1936 Olympics, his swimming career was cut short by World War II. He went on to become a naval officer, invent the nylon swimsuit, and faciliate the construction of public pools across Chicago. Today, at age 90, he swims 45 minutes every morning before going into his office!
