The July 2025 Washington Post article "Want to keep your brain sharp as you age?

• "regular moderate- to high-intensity physical exercise" — aerobic exercise, resistance training, stretching, and balance work
• "adherence to the MIND diet" — the Mediterranean-DASH Intervention for Neurodegenerative Delay
• "cognitive challenge" — exercises to help stimulate attention, brain speed, memory, people skills, navigation, and intelligence
• "social engagement" — friendships, meetings, etc
