Being “blind as a bat” means not being blind at all. While many use echolocation to navigate, all of them can see.
Poinsettias won’t kill you or your pets, though you still shouldn’t eat them. The flowers might make you a bit sick with some gastrointestinal issues.

Sharks can and do get cancer. The myth that they don’t was created by I. William Lane to sell shark cartilage as a cancer treatment.

Hair and fingernails do not keep growing once someone dies. Instead, the skin shrinks, giving the appearance of further growth.
People don’t use “just 10%” of their brains. We use the entire brain for different processes at different times. We couldn’t survive if we scooped out 90% of it.

Only a small percentage of people with Tourette syndrome randomly yell out swear words — it actually encompasses a lot more than that, including involuntary movements and different sound tics. The swearing tic is called coprolalia.
Microwave radiation won’t cause cancer, it just heats food up. In fact only a few types of radiation cause cancer, and these depend on the dose — just like radiation from the sun can cause skin cancer but just enough helps your body make Vitamin D.
Many people would call the dinosaur below a Brontosaurus — even Michael Crichton did in Jurassic Park — but it is actually called the Apatosaurus. The myth was started by two feuding paleontologists during the Bone Wars, 130 years ago.

It’s a myth that McDonald’s burgers don’t rot. Actually they will rot given the right conditions — water and warmth for the microbes that break the food down.
You are not born with all of the brain cells you will ever have. There is ample evidence that the brain continues to produce new cells in at least a few brain regions well into adulthood, through a process called neurogenesis.
It is possible to stand an egg on its head on any day of the year, not just on the Spring Equinox. It just requires a skilled egg handler and a textured egg shell.
The Northern Hemisphere of the Earth is not closer to the sun when it is summer. It is warmer in the US during summer because we are tilted toward the sun, so its energy hits us more directly.
The Great Wall of China isn’t the only man-made structure visible from space. Depending on your definition of space, either you can still see other man-made structures, or you can’t see it or other structures. From something like the Moon, you can only see our lights.
