I teach economics at a local community college. A few semesters ago, I gave an assignment to ask an "older person" when he bought his first new car and how much it cost. I intended to use the Consumer Price Index to calculate the current day price and help the students understand a little more about inflation and changing prices.
I was expecting answers such as 1934, $350; or 1940, $500---what I got from the first student was 1973, $4,000.
I asked this young lady whom she had asked for information, her answer was,
"My mom. She's real old ... almost 40." (I was 42 at the time.)
I never gave this assignment again.
