Adult Birds Don’t Abandon Their Babies

If you ever come across a baby bird alone, a vague memory of your mother might have popped into your head telling you not to touch it because the mother would abandon the baby. Mom was wrong. Birds have a terrible sense of smell and probably wouldn’t know if a human touched them or not.

After a long day in the pool, you may notice that your hands are really wrinkly. Most people believe that it is from the overexposure to water, but that’s not true. It’s actually due to our “autonomic nervous system” and it is something that has evolved from our ancient ancestors.

Believe it or not, but the term “420” has absolutely nothing to do with smoking marijuana. It’s actually a Police code in Los Angeles that means “juvenile disturbance.”

Your Nails And Hair Do Not Keep Growing When You Die

The myth that your hair and nails continuing growing after you die is totally false. Once your heart stops beating it only take about seven minutes for your nerve cells to die.
