40 years old (Born on December 30, 1984)
Happy birthday, LeBron! You're the only person who ages backward—from Rookie of the Year in 2004 to four NBA championships and counting. Your moves stay timeless while your hairline has its ups and downs—a worthy sacrifice for basketball immortality.Throughout changing jerseys from Cleveland to Miami, back again, then lighting up Los Angeles—your dunks have defied gravity as if you're forever stuck at age 20. Here's hoping you celebrate with a triple-double cake: layers of MVP skills topped off by candles representing every record you've shattered lately. Enjoy another year being King James; greatness doesn't take breaks—but today maybe chill on defense a little?
