The health damage of chlorine and bromine are cumulative. The younger the person, the more likely they will develop serious, permanent or fatal disease, birth defects of their own children and the other extremely harmful health effects. Compounding this is that young children tend to swallow more water in a swimming pool.
While you may be so old that filling your body with permanent toxins and dioxins increasingly is a risk you will continue to take, it is unthinkable to have children swimming in such water with the long term devastating health damage well known.
One recent study revealed that a non-smoker with a chlorinated pool is over twice as likely to develop cancer as a heavy smoker without a pool. The high number of pools and spas in the United States may well be the reason that cancer rates in deaths in the United States generally are 200% to 600% higher than other countries, with similar differences in many other degenerative diseases. Many Americans are putting toxic waste pits of the most powerful toxins and carcinogens in the world in their backyards and then swimming in it.
