Limits of models and real-life variability

Roger Whitney explores one of the most overlooked variables in retirement planning: longevity, and how assuming you’ll live too long can quietly force you to save more, spend less, and potentially miss out on life. Through a conversation with Dr. Bobby Du Bois, he challenges default planning assumptions, walks through the real trade-offs, and introduces a practical way to think about lifespan so you can better align your money with how you actually want to live.
