Web Desk: The major stress for the people now-a-days is aging, sometime they even focus more on the physical act of aging.
The body part which gets older faster is your head. This happens because of a relatively theory that was developed by Einstein.
A research was conducted at the National Institute of Standards and Technology, they wished to test that theory in a smaller scale at just a one-foot difference. The atomic clocks that were used, tick as a single aluminum ions vibrates between two energy levels over one million billion times per second.
It revealed that if time moves faster at a difference of only a foot, it definitely goes faster at the height difference between your head and your feet, making your head the oldest part of your body.
