"Unlocking Better Sleep and Fitness Age: A Week in Well+Being"
This week's Well+Being newsletter covers the concept of "fitness age" and a calculator to assess how well your body is aging, along with tips for better sleep including a short-term sleep experiment to deepen sleep and limit wakeful periods. The newsletter also recaps the New Year's Tuneup articles and shares joyful stories, such as an NBA player reuniting a lost dog with its owner and a comic about finding joy.
