Our life is like a river. It's flowing all the time.
In the river water is flowing every second and changing its location. In our life time is running every second and changing our body's autonomy and it never stops. We call it aging or getting old.
God has created Mother Nature. If we follow Mother Nature and eat raw fruits and vegetables we cannot get sick. Our body has its healing power within us. We get sick only because we go against Mother Nature. We cook vegetables according to our taste and sometimes it's harmful for our body. It is said that the tasty food is a poison and food which has no taste is a medicine for us.
Stay healthy and enjoy.
