### Time Does Not Accelerate With Age (or Does It?)

The word accelerate means the "rate of change of velocity." Decelerate is the negative of accelerate. The word velocity is a "vector measurement of the rate and direction of motion." The word speed is rate of motion without regard to direction. Both speed and velocity is the distance travelled per time unit.

It is often said that time seems to speed up as we get older.
Actually, it doesn't just seem to, it actually does. When you
are four years old, it feels like it takes forever until you
become five, and that's because that additional year is 25%
of your life. But going from age fifty to fifty-one is just
2% of your life. In other words, as we get older, each year
does pass by faster because it is an ever-increasingly smaller
percentage of our lives."
