Let's make this birthday one to remember.

64 years old (Born on March 20, 1961)

Happy Birthday, Sara Wheeler! May your special day be filled with adventures as thrilling and memorable as your journeys through Antarctica in "Terra Incognita." Your fearless exploration of icy terrains has inspired countless readers to embrace curiosity—and perhaps invest in warmer socks.

From unraveling the fascinating life of Apsley Cherry-Garrard in "Cherry," you've shown us that history can indeed be cooler than icebergs. Here's hoping this year brings you more exciting travels, captivating stories, and fewer encounters with frostbite. Cheers to another chapter full of laughter, discovery—and plenty more penguin anecdotes for future books!
