If you never cut it, the number of miles long your hair could grow to by the time you reach the age of 77.

Posted by: Skeptic at April 10, 2009 2:08 AMIt is a useful ability to be able to make plausible estimates with little exact data but common knowledge. The writer of this drivel would be well to practice this. For example hair grows around 1 mm/day (to within an order of magnitude or less). About 30 meters is rather less than 690 miles.
