The most effective way to dumb down the population (after smartphones) is vaccination. Thimerosal is a cheap and highly effective vaccine preservative favored by the Pharmaceutical cartels because it means vaccines can be stored without refrigeration. There are alternatives but they are more expensive and negatively impact profits.
If you have received your full regimen of vaccines you are probably brain damaged to some degree. If you are a parent you can ameliorate some of the impact by delaying and spacing out vaccinations as much as possible. If your doctor tells you it doesn’t make a difference he is only repeating what the pharmaceutical rep has told him and you might want to find another (preferably older) doctor. Also supplementing with vitamin c before and after vaccination and a daily dose of MSM will help the body to remove mercury and other heavy metals from the body (this can also reverse some of the brain damage). There is also evidence that vaccinations cause less problems in summer than winter, this may be because of more vitamin D in the body? I’m not anti-vaccination, some work (smallpox, rabies), most are like the new iphones, just money makers.
