What if getting older doesn’t have to mean losing your memory? Learn how neuroplasticity, healthy habits, and simple memory exercises can help keep your brain strong at any age. Summary: We often assume that getting older means our memory and brain function will inevitably decline—but emerging science tells a more hopeful story. On this episode of The Science of Happiness, we’ll explore how neuroplasticity, along with practices like memory exercises, stress reduction, sleep, exercise, and finding a sense of purpose, can support brain health as we age.  How to Remember Where You Parked: Pause before you walk away: Take a moment to look at your car and notice your surroundings. Identify your location: Pay attention to the floor, row, section, level, or nearby landmarks. Create a funny image: Turn the location into a memorable mental picture. For example, if you’re parked in section 4B, imagine four bears sitting inside your car. Make it vivid: The sillier, stranger, or more ridiculous the image, the better. Let yourself have fun with it. Take a mental snapshot: As you walk away, look back at your car and surroundings and imagine the funny scene there. Use the image to find your car: When it’s time to leave, bring the funny image back to mind and use it to recall your section, floor, or location. Scroll down for a transcription of this episode.

  • Welcome to the Science of Happiness.

  • I'm Shuka Kalantari.

  • Today we're exploring the science of memory and challenging

  • some of the myths about what happens to our brains as we age.

  • I just sort of went with the flow of that narrative of, yeah, you get older, things start getting a little fuzzier.

  • That's just what happens.

  • You start forgetting stuff.

  • Recent surveys by the World Alzheimer's Report revealed

  • that about 80% of us think that dementia is a normal part of aging, but it isn't.

  • I think my personal complacency with that opinion didn't serve me well.

  • We'll hear from Crystal Lewis, who's turning 41 soon, a time when some of us might start noticing changes in our memory.

  • When I was young, I had a wicked memory and very detailed, very intricate, and sometimes even like photographic.

  • That has since changed.

  • Crystal recently tried a series of games designed to strengthen memory.

  • It almost felt like an assignment in a way.

  • Like, okay, I have an objective and I want to make sure that I am being as present and observant as possible.

  • The games were developed by Dr. Majid Fatuhi as part of his approach to supporting brain function.

  • Just because you get older, it doesn't mean your brain will fade.

  • And if you take specific actions, you can indeed maintain your brain function at a reasonable level or improve it.

  • And that's what we did in my brain center.
