When you’re a child the summer holidays can seem to last forever, but as we get older six weeks can fly by.

To a ten-year-old, a year is only 10% of their life, (making for a slightly more tolerable wait), and to a 20-year-old it is only 5%. On the logarithmic scale, for a 20-year-old to experience the same proportional increase in age that a two-year-old experiences between birthdays, they would have to wait until they turned 30. Given this view point it’s not surprising that time appears to accelerate as we grow older.
