 Okay, yeah, let me just speak generally about little aberrations on blood tests. And we have these norms, and now we share blood tests with patients, and often patients will go home and look at the range or see an alert, like this is high, this is low, and that'll be a source of great consternation to them. And I'm not saying that they shouldn't, they should just listen to their doctors and not bother to engage in enlightened self-care.
