Counting To A Billion
If a person counted at the rate of 100 numbers a minute and kept counting for eight hours a day, five days a week, it would take a little over 4 weeks to count to one million and just over 80 years to reach a billion. But if you did this, it would only take 15 minutes to drive the person sitting next to you completely batty.
