The chemical energy in our food can also be converted to mechanical energy in the form of muscle movement and it provides us energy to travel and move from one place to another pace. The entire energy is not converted to mechanical though, it is also converted into heat energy.
Explanation:
It is given that,
Mass, 
Acceleration due to gravity, 
Acceleration due to gravity is given by :
r = distance from head
r = 1.42 m
So, at the distance of 1.42 meters from the head its gravitational pull on you match that of Earth's. Hence, this is the required solution.
