While you may have thought that the colorful bristles on your toothbrush are just yet another marketing gimmick, this seemingly pointless addition actually serves a real purpose.

So if I try to save your life, but you see that it will make you uncomfortable, can I assume you will pass on the help?
Yes, had me totally confused .
