Water in the human body

I have noticed that, as I have grown older, my body needs more and more water to feel fit.

Also that, as soon as I drink water, the whole of my body responds - as if water has spread instantly through the whole system.

Thesis: water does not travel only physically through the system, but each cell has an optimal amount of water that it needs; as soon as this is exceeded, it immediately passes on the excess water to the neighbouring cell(s).

That is why one of the simplest cures for constipation is to drink several glasses of water - and, long before the water has travelled physically through the stomach and duodenum and the small and large intestines, it will moisten the waste sitting dry and difficult to eliminate in or near the rectum, and enable the elimination of the waste.

Conclusion: most anti-constipation pills are unnecessary.
