Question 3

Question How old are you?

Answer We measure the time not like you in astronomical years and in the revolve of the earth around sun, because we usually live beneath the surface of the planet. Our time measurement depends on periodically returning cycles in the earth magnetic field and according to this (and said  with your numbers) I´m today - let me calculate - 57,653 cycles old. I have reached my adult phase and my awareness 16,337 cycles ago (this is a very important date for us.) According to your human time scale I´m around 28 years old.
