Hey... The mexicans are still putting lead in candy. The FDA may have recently changed allowable levels of lead in candy for the US, mainly sold near the mexican border states. The lead issue came about because black kids were eating chipped paint containing lead in apartments (cheaper than Dorito's and tastes just as good).
There have been notable changes in behavior and health since the 1960s. Not all are due to the the counter-culture. For example, people spoke differently before the 1960. Their voices sounded better, more levelheaded. Old films testify to this fact. Since that time, deep, manly voices have all but disappeared. Since the 1960s, it seems that the average person's health, behavior, and intelligence have degraded significantly. Blacks appear to be especially affected, though they weren't exactly an impressive bunch before that time. Lower class whites have also become more and more thrashy and dumb. Lead is probably the biggest factor in this general decline. I won't be surprised if the same heavy metal that once stupefied and ruined Ancient Rome will also ruin America. Estrogens in the water supply, originating from the non-degradable remnants of female contraceptives, are having a feminizing effect on animal life. Average serum estrogen has increased, and testosterone and sperm levels keep declining precipitously. If current rates of decline in sperm quality continue, all men will be infertile by 2060. We have an epidemic of mental illness and physical illness. Not all of this is attributable to a sedentary lifestyle. Sometimes toxins play a big role in human stupidity. Lead induced dullness and insanity is the most likely reason for the success Liberalism has been having in the last 50 years.
I didn't even know they had heavy metal bands during Roman times. OK, now I have to ask you for your sources for this information. If you are talking about men in my generation being sterile by 2060 I can see how you could be right if the fountain of youth isn't found soon. But all men will be sterile (men don't become infertile) by 2060? That requires a credible source to be believed.
