If you had to guess what the key to living to a triple digit age was, what would you say? Clean eating? Exercise? What if I told you it was drinking light beer?

Not just any light beer, mind you, but Coors Light specifically.

That's what Andrew Slavonic in McMurray, Pennsylvania credits his long life to. The World War II Air Force veteran recently celebrated his 101st birthday and gave up his secret. Every day at 4 P.M., he drinks a Coors Light.

According to his son, Andrew makes his own breakfast and lunch everyday, reads the newspaper in his office, and grabs a beer out of the fridge at 4 o'clock. His ritual started in 1996 with regular Coors, he switched to the light stuff about seven years later.
