"Just look at nature. Look at your family, ancestors who lived to be the oldest. " Yes a good idea. The home for elders are now filled with dementia. My mother that was quite vital a few years ago, has now a crippled back. Her health simply withered within a couple of years. You would not recognize her. No Iodine involved last years. Her brain doesn't work very well anymore, sorry to say. In my opinion we have other challenges today with toxins than was present lets say 50 years ago.
