Water in Dialysis
To survive after both kidneys have failed, one must either have a kidney graft or be treated by dialysis regularly for the rest of one's life. Dialysis nowadays usually involves rinsing out the peritoneal cavity (the space between the intestines and the abdominal wall) with several gallons of fluid two or three times a week to remove body wastes which would normally be carried away in the urine.

Alzheimer's Disease
Alzheimer's disease (once called senile dementia), is a dreaded condition that afflicts about one in three people in their 80s. The gradual accumulation of aluminum in the brain over a lifetime has been thought by many experts to be a contributory cause to the disease, if not the main one.
That view has been universal, however. Other experts have argued that there is no relationship between the amount of aluminum in the brain and the degree of the dementia. Their objection is now weakened by research reported in the Lancet that used the newest and most refined method (nuclear magnetic resonance) for studying the chemistry of the brain.
