If I had a option to update human body I will firstly update the brain because there is too much differences we see in all the life and everyone thinking of themselves and no able to work properly and we see he is a good brain working problem.so I update equal storing capacity on all the brain so there will be no dissimilarity we see.

The next thing I like to update is a wings should be connect on the human body because wings will be very important thing in all the person living in the world.if I update wings then people can surely visit that place wherever they wanted to go and also without wasting time we can travel all over the world and there should be no visas to the country also.

Thanks for Readings
