Science says cognitive decline is not inevitable. Your brain responds to every choice you make — and researchers have found that people with healthy daily habits have brains that function up to eight years younger than their actual age. From the way you move to the way you sleep, eat, and connect with others, these are the simple, proven daily habits that protect your brain, sharpen your memory, and keep your mind strong for decades to come. Start with just one — your future self will thank you.
