Science

Here's how science works. Scientist(s) A do a study. They publish it in a journal after being reviewed by Scientist(s) B,C,D,etc. If you wish to reject the conclusions of A's study, then get out your relevant qualifications,  and kindly ask a peer-reviewed journal to post your detailed rejection. Or at least make an argument grounded in common sense. Until then, you accept what Scientist(s) A have to say, even if that involves ridiculous things like relativity and space/time, or quantum physics, or that young people have different neurochemistries that enforce different sleep cycles.
