At 78, Retired Professor Shares Daily Habits for Maintaining ‘Razor Sharp’ Memory

At 78 years old, Anthony D. Fredericks, Ed.D., professor emeritus of education at York College of Pennsylvania, says his memory remains “razor sharp” thanks to a set of intentional daily practices. After more than three decades in academia, Fredericks continues to write books — more than 175 to date — give presentations, and blog about psychology. He credits five daily habits with keeping his cognitive skills strong and his mind engaged.

Fredericks emphasizes the importance of social interaction, noting that staying connected helps reduce depression and stress, both linked to memory decline. He and his wife maintain an active social life, dining with friends, volunteering at a regional art association, and participating in a local social club.

As a lifelong learner, Fredericks reads widely to fuel his curiosity. He is currently exploring a book on the history of papyrus and cites the story of Marc Antony gifting Cleopatra 200,000 papyrus books as a favorite fact.

Organization also plays a key role. Fredericks uses a color-coded Post-it system to manage daily responsibilities — yellow for writing projects, blue for book chapters, green for medical reminders, orange for household tasks, and pink for errands.

Daily physical activity is another cornerstone. He alternates swimming laps at a community center with one- to two-mile walks, stressing that even short bouts of exercise can improve brain function.

Finally, Fredericks underscores the value of a nutrient-rich diet, hydration, and consistent sleep. He prioritizes leafy greens, berries, lean proteins, omega-3-rich fish, and ensures at least seven hours of sleep per night alongside proper hydration.
