Going fast is not neccesarily going down hill

Here is why time seems to go faster as you get older. It's because each moment of time is a smaller percentage of your life. one year in the life of a 1 year old kid is a life time. one year in the life of a 10 year old is one tenth of his life. A year in the life of a 30 year old is one 30th of their lifetime. one year in the life of a 60 Year old is only 1/60th of a lifetime. and a year in the life of someone age 100 is only 1 percent of their life. So it makes sense that time seems to go faster as we age.
