Mentalrobics™

You exercise your body to stay physically in shape, so why shouldn't you exercise your brain to stay mentally fit? With these daily exercises you will learn how to flex your mind, improve your creativity and boost your memory. As with any exercise, repetition is necessary for you to see improvement, so pick your favorite exercises from our daily suggestions and repeat them as desired. Try to do some mentalrobics every single day!

As we go about our daily lives, we are constantly making decisions based on guesses and estimates. This exercise will help you improve your ability to make educated guesses about distance.

When you are estimating each answer, try to pay attention to how you are solving the problem. Are you guessing the whole number or are you trying to calculate it based on smaller guesses? Avoid using a calculator or pen and paper until after you have made your estimate.

1. Distance to the moon in miles
2. Length of a AA battery in millimeters
3. Thickness of a standard #2 pencil in inches
4. Height of a stack of a million dollar bills in feet

The answers are listed below in backwards order. Don't cheat!
