What we have today and what do we need it is all about our brain and body need .we should travel interval between birth and death.
We always feel our life amazing and seriously but it is not truth ,it is game of our body mass and brain .
Science is just name but real truth of nature is many more.we are bounded of many kinds of energy and they are playing with us .
Everything is natural and it was created naturally and mysteriously.it will be create the other energy like our life and earth and so on ..
Never take anything seriously ,live our life peacefully ...
