The work everyone has to do ...
Number one breathing (clean air preferable)
Number two drinking (none toxic water)
Number three eating (hopefully with some nutrition value)
Number four digesting (a nicer way said, instead using a strange emoji)
Number five moving (hopefully with a completely functional body)
Number six using all our brains (gut, brain what else) & our senses, body together as a whole
Nothing more really - to be part of this planet, to be part of life.
