If you thought measuring your biological age required an expensive trip to the lab, think again. We are fans of this simple test you can do at home in a couple of minutes: “Biological Age Calculator.” By inputting your age and sex alongside results from physical assessments – including your max pushups, sit and reach distance, balance timing, and a reaction time test – you can estimate how well your body is functioning compared to your chronological age. After securing that baseline, consider extending your “joyspan,” a concept explored in: “How to Add Life to Your Years (Not Just Years to Your Life).” The author recommends prioritizing daily habits that naturally stimulate your mind and body while concurrently supporting long-term health. According to the Harvard Study of Adult Development, strong social relationships remain one of the most consistent predictors of a longer life. Other engaging activities offer similar protective benefits; playing recreational tennis is associated with significant increases in life expectancy, and spending consistent time in nature may lower cortisol levels. Even adopting a dog could lower your blood pressure and provide a daily dose of oxytocin. You can apply these principles by integrating play, social connection, and outdoor hobbies directly into your standard weekly training schedule.
