Let's make this birthday one to remember.

64 years old (Born on January 14, 1961)

Happy Birthday, Rob! You've scaled Everest five times—clearly, blowing out candles on a cake is child's play compared to braving the icy winds at 29,000 feet. Your legendary climbs have inspired countless adventurers and couch potatoes alike; after all, not everyone can say they've stood atop Earth's highest peak more often than most people visit their dentist.

Though your final climb in '96 became part of mountaineering lore forevermore, today we celebrate every summit you conquered with courage and humor intact. Wherever you are now—probably scouting new peaks—we hope you're enjoying breathtaking views without frostbite worries. Cheers to an eternal legend!
