Let's make this birthday one to remember.

84 years old (Born on September 30, 1940)

Happy birthday, Harry Jerome! You've sprinted your way through history with more speed than most of us can muster running toward cake. Winning bronze in the 100 meters at the 1964 Olympics and then taking gold at the Pan American Games in 1967—wow! Talk about putting candles on your rival's birthday cakes to shame!

You're proof that age really is just a number. Luckily for you, so are seconds—if only we normal folks could cover ground as swiftly as you do birthdays. Keep racing ahead, champ; may your celebrations always be faster than your competitors' feet!
