Happy Birthday, Katherine Grainger! You've rowed your way into Olympic history with such grace and determination that even the Thames applauds you. From Sydney to Beijing, Athens to London, you've collected medals like they're going out of style—though we all know gold never does.Your incredible victory at the 2012 London Olympics remains unforgettable; after three silvers, you finally struck gold and showed us all that persistence truly pays off. May your birthday celebrations be as smooth as your rowing stroke and filled with laughter brighter than any medal podium. Here's to another year of golden moments ahead!
