87 years old (Born on April 13, 1937)
Happy Birthday, Donald R. Pierce! You've galloped through life with style and speed, leaving the competition in your dust at legendary races like the Los Angeles Handicap and Santa Anita Derby. Your induction into the National Museum of Racing Hall of Fame in 2010 was just another victory lap for a jockey who always knew how to ride high.Though you've hung up your racing silks, we bet you're still leading by lengths when it comes to celebrating birthdays. May this year bring you as much excitement as crossing that finish line first—just remember not to blow out those candles too fast; pace yourself!
