You may have seen the bright yellow bracelets. They're called "Live Strong" wrist bands. They sell for a dollar a piece and the money goes to the Lance Armstrong Foundation for Cancer Research. They're so popular they're selling faster than the manufacturer can get them out, but now, some hospitals are trying to get the word out that those bracelets could be hazardous to your health.
The wristbands are yellow and at some hospitals a yellow wristband means "do not resuscitate." so, some hospitals are warning people that if you're going into the hospital, take the wrist band off or cover it with tape so as to cut the possible risk of a deadly mistake.
