A Source of Good Health was an installation made up of elements of other works which were about swimming pools. The first element was called It Means As Much To Me As It Does To You and it can be seen here. The second element was called Bottoms Up which can be seen here. The third element was called Gene Pool which can be seen here. All the elements came together with a sign saying THIS IS THE SHALLOW END DO NOT DIVE which referred to a previous work but also to the fact that the water that filled the bottles in Gene Pool was taken from the shallow end of a swimming pool.
