You have been given a bank account that contains $1,000 under the condition that you cannot withdraw the principal (the original $1,000) for 30 years. The money will earn 10% interest each year. A special rule, however, allows you to withdraw the interest each year to spend on whatever you wish. Would you rather withdraw and spend the interest every year before getting the original principal, or keep the money in the bank for 30 years and spend it then?
