Train your brain.

If you’re right handed, try brushing your teeth with your left. This is one simple “neurobic” exercise. A neurobic exercise involves one or more of your senses. When you change a routine, you’re stimulating a different part of your brain. According to Lawrence Katz, Ph.D. and author of “Keep Your Brain Alive,” these mental exercises help fight off the effects of mental aging and help to preserve and grow brain cells. Here are a few more simple neurobics.

• Take a shower with your eyes closed.
• Eat a meal with your family in silence, use only visual cues.
• Take a new route to work.
• Rearrange your desk or workspace.

If you really want to challenge your mental routine, try using your other hand for your computer mouse or to write. Just think how young your brain will look, not to mention your penmanship.
