Just curious, has anyone ever seen a calculation determining what the chances are that you (or I) have drank the same molecule of water as someone in history? You'd have to figure just how much water there is on Earth, including the oceans, but probably some of the deepest groundwater could be ignored, since a lot of it has been there thousands of years anyway. You'd also have to assume a daily intake volume, total ages of each person, and probably the number of molecules of water per some unit volume.
I bet there is a "decent" chance that sometime in my life I have consumed a molecule or two of water that was once drank by Julius Ceasar, for instance. :)
I try not to think about that. Prolly some of the water he pee'd in <yech>

Wow....what a kewl thing to think of. I'm gonna have to run this by some people at work.....wouldn't it be neat if I drank a molocule of water once passed through the bowels of Sir Isaac Newton? Or Socrates? Or even Jesus?

Makes me realize just how perfect this world is :p

Moles per head = (4,540 grams) / (18 grams/mole) = 252.22 moles
Molecules per mole = 6.022*10^23 * 252.22 moles = 1.519*10^26 molecules
Ok, I found this online, a calculation to determine the number of molecules in your brain, assuming it is all water and weighs 10 pounds. Working from this, since water is 8.33 lbs/gal, total molecules of water in one gallon is near 1.265*10^26. I think I am going to need a very big calculator... :)

A substantial amount of carbon dioxide and water vapor is in exhaled breath. In a warm climate like that in which Jesus lived, about 8 pints of water per day is carried away in the breath. Add to that about 3 pints of water lost by sweating. Of course, during the early days of His 12,000 days on Earth, He was a small child with less respiration. Still, this totals approximately 10,000 gallons of moisture given up to the atmosphere during His life! This is all water that was physically part of His body, and which had left It as evaporated sweat and respiration. The figures regarding the carbon dioxide in His exhaled breath are equally substantial.
That amount of water which had earlier been part of His body, and had left it prior to the Crucifixion, involves about 1.2 x 10^30 molecules. Even when His spirit arose after the crucifixion, these water molecules remained on Earth. They joined natural atmospheric, surface, and underground water. Those molecules eventually found their ways into streams, lakes, oceans, and atmospheric clouds. Those molecules became dispersed and soon were in rain falling all over the planet (soon meaning within 60-100 years.) After a 2000 year period of such mixing, statistical analysis based on reasonable assumptions clearly establishes a very uniform distribution of those molecules today over the entire Earth.
Totaling up all the water on, in and above the Earth, there are about 2.8 x 10^20 gallons or 3.3 x 10^46 molecules of water in existence. Dividing indicates that in every single ounce of modern water, there are 35,000,000 molecules of water which had at one time been part of the body or blood of Jesus! That obviously includes Sacramental Wine. That is, EVERY ounce of Sacramental wine contains many of the same molecules which had flowed through the veins of Jesus when He walked the Earth!
(The author finds this a staggering statement, but scientifically absolutely true!)
Well, I found someone else who did similar calculations I guess. I was coming up with a crazy number too, something like 1 molecule out of every 3.5 billion, which is tens of thousands of molecules per every gallon we drink. Amazing. Currently I have thousands of molecules in my body that once made up not only Jesus, but Sacrates, Mohammed, Hitler, etc. :eek: :eek: :eek:

I wonder how much of the exact same water I have drank more than once... :o

"While parts of the hydrologic cycle occur on a time scale of hours or days, other parts take centuries. The average residence time of water in the ocean (the length of time thaqn an individual molecule spends circulating in the ocean before it evaporates and starts through the hydrologic cycle again) is about 3,000 years. In the deepest ocean trenches, movement is almost nonexistent and water may remain undistrubed for tens of thousands of years."
From: Environmental Science, 8th edition, W.P. Cunningham, M.A. Cunninngham & B. Saigo, eds
So I guess that kinda answers your question: It depends.
Maybe googling "residence time" of water and hydrological cycle might help you out.

And of course alll of this is completely and 100% hypothetical. For all you know there could be alien seeders floating in the atmosphere that take out the water - dissipate it in some vast dissipater and then replicate an equal amount of water
