1)I couldn't let this go. Water does not have fat in it...it doesn't make you fat. Yes it has minute trace amount of minerals but not enough to effect you. Tap water does have additives such as Floride, but thats to benefit healthy teeth and gums.
2) The women in Cali died from water intoxication. She was in a contest called "hold your wee for a wii" a playstation game & drank gallons very fast. She died from how fast she drank the water. Our body is regulating system of of chemical balances. By drinking gallons in a short period of time, she through off that balance. What happens is the the cells absorb the water in our system. This leaves salt & impurites aka electrolytes, out side the cells. The imbalance of the cells slow down the regulartory systems in the body such as the kidneys and most importantly the brain. Cells can absorb too much water to the point it can burts if pressure is not eleviated (urination) or balance not restored. Her kidneys and brain swelled and since the brain is encased in the skull, the swelling had no where to expand. thus her death days later.
