“Everyone has to stay out of poison ivy.”
Poison ivy isn’t a poison or an ivy. It is an allergen that affects some people causing severe itching and swelling. Roughly half of the world’s population is allergic to poison ivy.

“Beware of toxic chemicals.”
By itself, this is a meaningless phrase. Many chemicals are both safe and toxic, it is dependent on the quantity, strength and how that chemical combines with others. Take aspirin for example.

So keep learning and growing your brain, search in our Virtual Collection through articles on neurology such as “7 Brain Myths” from Toronto Star writer Alanna Mitchell.
“Have you heard that bananas imported from the Caribbean are contaminated with necrotizing faciitis, a bacteria that consumes human flesh?”
If you have, don’t repeat it, because you will be passing along another urban legend. These stories can be humourous, intriguing, bizarre or disgusting, they surface from time to time and are repeated endlessly. Read The Baby on the Car Roof and The Cat in the Dryer both by Thomas J.
