- A crying baby can damage your hearing permanently. Ear damage can occur at 85 decibels and a baby can cry at levels up to 90 decibels.
- For about six to seven months after birth, a baby can breathe at the same time. This ability was beneficial in the watery environment of the womb.
- We can almost unlimited distances, depending on the light coming from the object. Five planets are visible with the human eye- Mercury, Venus, Mars, Jupiter and Saturn. But it’s a myth that the Great Wall of China can be seen from space.
- The heart is not on the left side of our chests. Imagine a line drawn down the middle of your body, most of your heart is on the right side of the line. Only the top of the heart is on the left. The heart is not straight up and down, in our bodies, but on an angle.
- On average, you lose about 200 hairs per day.

- The average person has 10,000 tastebuds. The life span of a tastebud is seven to 10 days. By age 60, we’ve lost half our tastebuds.

Kissing can make you live longer. Research shows it lowers stress and cholesterol levels.
