go visit a doctor.

edit: lol. downvotes on friendly reminder, what a classic.

my friend was not sure what everyone sees on 3d TVs. then got rid of it. later it turned out it was because of eye cancer.

take care.

FWIW, your first line by itself does not come off as a friendly reminder at all. If that’s all that was there before your edit, I can understand why it inspired some reactions. The edit suggesting it’s everyone else’s fault isn’t going to help either, but I will take your comment as well intentioned and vote it up, it sucks your friend had eye cancer, and it’s a good idea to get preventative checkups.

Even as a friendly reminder, an implication of your first line is that binaural beats should work, and that if it doesn’t something is wrong. Did you mean to imply that? If so do you have an answer to the question about scientific support?
