caffeine
the popular opinions tend to defend caffeine even as they clearly state dangers, especially in coffee, but then the popular opinions are driven by economic pressures (anytime he reads anything, especially a scientific study, he wonders how much influence the people selling the product had in the study) and were once used to vehemently defend alcohol, tobacco, and even cocaine and once upon a time one could be put to death for suggesting the world was not flat and the earth was not the center of the universe, so popular opinion or even science, government, or law is not the final word on anything... even popular medical websites are quick to soften any ill effects of caffeine even as they list them... he wonders about the logic of defending anything that is universally regarded as not good for children, as if it is ok for the same bodies once the bodies are no longer growing and on their way to dying... but like most people, she trusts popular opinion, so she sees her doctors and increases her medications and changes her medications and continues consuming caffeine in large doses daily... he trusts his instincts and his body and knows he feels much better during periods of his life when he is not consuming caffeine daily...
