## Resource

Most longevity conversations focus on two things: living longer (lifespan) and living healthier (healthspan). But there's a third pillar almost nobody talks about. In this video, cardiovascular surgeon Dr. Jeremy London introduces timespan, the science of how you experience the time you have. Why does a year at 50 feel shorter than a summer at 7? Why do we reach our deathbeds feeling like we "just blinked"? And what can we actually do about it? In this episode, Dr. London breaks down: The Proportional Theory of Time, the mathematical reason why time speeds up as you age (and why you've already lived half your "felt" life by 17 or 18) The neuroscience of episodic memory, how your brain decides what gets recorded in 4K vs. what gets skipped The Reminiscence Bump: Why ages 15–25 feel richest in memory, and how to recreate that density 3 levers to reclaim your time perception: Flow, Presence, and Purpose My Newsletter⁠ https://www.drjeremylondon.com/newsletter⁠ Thank you to our sponsors Function: www.functionhealth.com/london LMNT: www.drinklmnt.com/london My Social Media Instagram: ⁠https://www.instagram.com/drjeremylondon/ ⁠ TikTok: ⁠https://www.tiktok.com/@drjeremylondon⁠ Facebook:⁠ https://www.facebook.com/drjeremylondonmd ⁠ ** The information in this video is not intended nor implied to be a substitute for professional medical advice, diagnosis or treatment.
