You know this already.

Read this girls. It doesnt tell you anything you don't know but it's good brain fodder for the moment before you forget it and do the exact opposite even though you know the opposite is the opposite of what you should be doing, not just because the article said so, but because you know so.
I shouldn't bother telling you, right? Because you heard it before, and a reminder will only be a mild jolt in your memory, that will trigger the sickening feeling that you know this anyway, but forgot, then guilt will kick in because you told yourself the last time that you should have remembered it the last time you forgot.
This sounds complicated but it makes sense, is perfectly sensible and every sane person would agree to its logic.
In other words, they know this already.
