These are not my photos, but here are two amazing revelations of diversity.
The first is a magnification of grains of sand…..yes, sand, the kind of sand you find on the beach. Did you have any idea that grains of sand were so diverse?
Then, you might have come across these amazing photos of snowflakes…..here is just one of them.
So, folks, if even grains of sand and snowflakes are so diverse, can you imagine how diverse more complex forms are….like lifeforms? Like human beings?
This is one of THE main purposes of the universe – to produce ever more uniqueness, ever more diversity
Heroes Not Zombies 
Amazing photos, especially the sand. As you say – these things are so diverse (and we would generally think of them as simple items). Then a human being, by comparison, must be trillions of times more complex.
No wonder there is no “one simple fix suits all” for the medical conditions that may affect us. No one tablet, etc.
Thank goodness for people who believe in Integrative Care ! Because many people would feel they were beyond help or any chance of improvement without this. The “go away and just take the tablets” approach simply fails people.
