Certainly this person is not a child or teenager. For example 15^{2} = 225 so someone who was 15 in the year 225 lived about 1800 years ago. I am 68 years old but I doubt I will be around in the year 68^{2} = 4624. Even someone who is 50 years old probably won't be around in the year 50^{2} = 2500. Find a number x so that x^{2} is a year when you will most likely be alive. Do you know someone who is x years old? When were they born? Harley
