The first thing we look for when exploring other planets is water, because where there is water, there is life. Water exists in oceans and air, in rivers and lakes, in icecaps and glaciers, in the ground as soil moisture and aquifers and even in you.
Water regulates body temperature, helps the body absorb nutrients, carries these nutrients and oxygen to cells and lubricates joints, tissues
and the spinal cord. Regular, proper hydration is one of the most important components for good physical and mental health.
