What're you talking about? It's a function of global trade lol.
Water only exists as atoms. There is no non-discrete water, it is inherently in reality discrete.
Atoms of water are measured in moles. Atoms are discrete units, a mole is just a certain number of them
Compare the percent of income required for seasonings and fresh fruits from around the world now vs 200 years ago.
Or just atoms of water
I believe there are about 55.508435 moles of H~2~O in a liter of water at sea level (basically assuming 1 liter of water = 1kg of water)
Why does it matter?
I had an ear infection, the doctor thought I was lying for pain killers(she said people my age shouldn't get ear infections, and I could've just used a hairdryer), I told her no the pain is fine I just want antibiotics so it doesn't get worse. She then decided to prescribe codeine and oral antiobiotics but not ear drops.
When I went to the pharmacist they filled the codeine prescription even though I didn't want it.
Nor the doctors themselves (well most are innocent, but there are a few who lobby with the AMA to help keep prices high so they keep getting paid)
you're right, it doesn't to me
