This week on Death Clock, Brent speaks with journalist and author Nicole Karlis about the connection between altruism and longevity. Nicole, author of Your Brain on Altruism, shares research-backed insights into how acts of kindness, generosity, and volunteering can positively impact both mental and physical health. They discuss how altruism isn't just about helping others – it also fosters a sense of purpose, strengthens community ties, and can even contribute to a longer, healthier life. Brent and Nicole explore the science behind these benefits, including studies showing that people who regularly give back experience lower stress levels, improved well-being, and even reduced risk of chronic diseases. Whether you're looking for a new perspective on well-being or simply interested in the science of giving, this episode offers compelling reasons to integrate more acts of kindness into daily life. Hope you enjoy.
