1. Your body is around 70% water.

2. In your lifetime you will produce - and shed - around forty gallons of skin!

3. When you’re born, your head is around a quarter of the length of your entire body. But by the
time you’re fully grown it is just one eighth.

4. You have about the same number of hairs on your body as a chimpanzee does - the only
difference is that yours are so short and fine they are almost invisible!

5. Around half the population of the world have eyelash mites - tiny creatures that live on your
eyelashes and eat dead skin cells. If you put your eyelash under a microscope, you might just see
one!

6. Men’s hair is about twice as thick as women’s.

7. Another difference between the sexes is that women blink twice as often as men.

8. A final difference is that women are better at smelling than men.

9. You can only taste something if your saliva can dissolve it - you can test this if you dry your
tongue before putting something on it!

10. You breathe in approximately ten thousand litres of air every single day\
