I also don't approve of otc teeth whiteners I would rather ask my dentist in Austin of http://www.theaustindentist.com for a teeth whitening treatment because it's safer. Besides, otc teeth whiteners aren't meant to be used daily and it doesn't have a lasting effect -- they are only preferable for special occasions like a party or an important photoshoot that will require you to show your teeth.

I love optical illusions, especially those two pictures in one optical illusion. I heard that two-picture types of optical illusion can say a lot about your personality, just like the "9 (or 10) dolphin picture and intimate couple" image that I saw from an arizona eye doctor's facebook page. If you saw the first dolphins then you have the innocence of a child, while seeing the intimate couple means that you have already experience a romantic relationship with the opposite gender. It's really cool when I think about it.

I can't remember where I saw it, but it's definitely here on this website: http://www.arizonaretinalspecialists.com/
