Happy Birthday, Grant Hackett! You're the only guy we know who can make swimming 1500 meters look easier than blowing out birthday candles. Your Olympic gold medals from Sydney 2000 and Athens 2004 still shine brighter than your swim cap under stadium lights. Honestly, we're pretty sure fish envy your freestyle technique.Even though you've hung up the goggles competitively, your legacy continues to inspire swimmers worldwide. May this birthday be filled with laughter, joy, and absolutely no chlorine in sight—unless it's in a poolside cocktail! Cheers to you, Grant; may you always stay afloat in happiness and success!
