A modern day luxury available for 25+ years is owning a refrigerator with water and ice in the door.
Having your own water distiller and pumping that clean water yo your fridge is the first step of living healthier.
Those that drink dirty water, which is 99+% of the world, "they" adapt to taste and smell and do not realize what their water taste like.
"IF" they leave their home for a 2-4 week vacation and then return to their dirty water, they may taste it for a day and then quickly accept the taste as normal.
It is actually amazing how long some people do live on dirty well water and the chemical city water. That alone is proof humans such as explained by Dr. Howard Hay, M.D. as little as 80 years ago were living to age 200+ and looked no different than their male children. Only the females died prematurely due to having children---while medical has reversed this by poisoning the males to the point the females on average outlive the males--- The number 1 problem the females have today is medical, they are realizing the old folks homes are not safe environments. In fact, the older a person becomes, the larger the target is on their back by many sources surrounding them, to the point they are best off staying far away from all organized gov/med and sadly even many pastors that work with lawyers and judges to take the properties away from the elderly that have no one protecting them from the predators.
