I may agree with you that this didn’t seem to be a problem 60 years ago. but the environment, food supply, air, water, is not what it was 60 years ago. We didn’t have that freaky modified wheat we have now. Granted alot of people don’t starve because they have altered the wheat to produce more per head…but that stuff messes with alot of our systems. They didn’t have Genetically modified Corn and Soy. These 3 things are in almost all the processed food. Most americans eat processed food. Even if you get the wheat berries and make your own bread you are still using the modified wheat. They didn’t have everything stored in plastic. We have no real idea what all the DDT and other pesticides that were used during my granparents era is having on the DNA of future generations. They were not using the level of antibiotics and growth hormones in the meat we eat now. Our envirnoment is so different than it was before. Scientifically they (who ever they are) can not prove or disprove whether these things are having an adverse affect on our brains and our bodies… but just cause you can’t find the cause doesn’t mean it isn’t causing something. I would be pretty niave to believe that all these chemicals in our air and water and food supply is not causing issues. True… I am adding one more to the mix…but if it allows me to function and my son to function in the environment I find myself in. It is what I must do.
