True or False: Science Myths Dispelled  
INFORMATIVE 

Tags: science, myths, true, false

Bras cause cancer? Waking a sleepwalker is fatal? Here are some of the more common science myths that might be fictitious.

	You have to have all 10 toes to walk FALSE - Walking with nine toes is less efficient, slower and shorter, but is still as effective as walking with 10 toes.
	Underwire bras can cause cancer FALSE - The bra-caused breast cancer theory is not supported by sufficient evidence. Commonly accepted breast cancer risk factors are generally things that affect endogenous hormone levels.
	Waking a sleepwalker may kill them FALSE - The chances of killing a sleepwalker due to the shock of sudden awakening, however, is about as likely as somebody expiring from a dream about dying.
	A cockroach can live with out its head TRUE - Headless cockroaches are capable of living for weeks. And it is not just the body that can survive decapitation; the lonely head can thrive, too, waving its antennae back and forth for several hours until it runs out of steam.
	Chocolate is poisonous to dogs TRUE - Chocolate's danger to dogs depends on its quantity and quality. Large dogs can usually handle a small amount of chocolate whereas the same helping could cause problems for Moose and his pint-size kin.
	Urinating on a jellyfish sting is an effective treatment FALSE - Although it worked for Monica on "Friends," urinating on a jellyfish sting can cause the person more pain. Urine can actually aggravate the jellyfish's stingers into releasing more venom
