The fastest reactions in our body (hydride shifts, very small rearrangement of atoms to maximize charge stability) take a mere picosecond. This nanosecond is 1000 times longer than a picosecond. Try to imagine that the molecules in your body are spinning at crazy frequencies and rearranging themselves incessantly at that speed.
