It is merely the sharing of scientific research from which all people can be educated, and some may find applicable and some may not. I share science with no intent to praise or condemn anyone. No one needs to feel bad if they never drank coffee, don't drink coffee, won't drink coffee. I don't expect people to go back in time with this information. Even with this information, some may choose not to have caffeine; and they're totally free to do however they please.
