time can do so much

You feel one year goes by quicker and quicker as you get older.
I didn't know there is a law which explains this phenomenon.

The law is called Janet's law.
One year for six-year -old kid means one-sixth of his life.
One year for sixty -year -old adult means one -sixtieth of his life.

Two months for six-year-old mean one year for sixty-year-old.

When you are a kid,everything is new and you feel time goes by slowly.
As you get grow older there is less and less new experience.
You don't have a surprise everyday.
So time goes by so quickly.

If you try to find brand-new things and keep curiosity, you may feel time goes by slowly like kids.
