It is very valid for everything in this world,what Newton said in his third law,"Every Action Has a Reaction in which magnitude is the same and the direction is opposite".

Science is a subject of life which is always changing and dependent on wise people's hypothesis and theories.

Life experience provides us feedback of our lives.On the other hand,trying to become an experienced person puts you in danger.We should let our selves get experience by the time only when your life is ready to provide it on the right time with the right people.

There are some facts we cannot explain by scientific methods such as life time bondage between mother and child.

The best events of our lives will be in next seconds...So always live with hopes to get the best things !

Death comes to you soon when you are afraid of it, so you have to live as you will not have to be afraid of death when your time comes for the leave. :)
