When everybody talks about their physical health, one important organ they forget is the brain. The brain needs to be exercised just like any other muscle in the body. Do everything you can to keep it active — read, write, learn new things, carry on intellectual conversations...don't just sit in front of a television or a computer and become a vegetable. You need to keep using those connections between nerves or they become unusable. A mind really is a terrible thing to waste.
