I was cleaning out my room the other day, stumbled across this piece of article (Grossology was an exhibit at the Singapore science centre in 2001, 10 years ago!). Some of the points are kinda shocking!

Grossology Trivia

1. Hydrochloric acid in your stomach is so strong that it can eat up stainless steel razor blades.

2. Your large intestine is about 1.5 meter long.

3. Every day you make 1-2 litre of urine. The amount depends on how hot it is outside, what you eat and how much you drink

4. You swallow about one litre of snot every day.

5. Earwax coats the inside of the ear canal to trap any nasty stuff like dirt, dust and bugs that get into your ear. People who live in big cities make more earwax.

6. The skin is the largest organ of the body. You shed skin every day to produce a whole new layer of skin every 28 days.

7. About ten billion tiny scales of skin rub off your body every day. In a lifetime, you could fill eight 2.5-kilogram flour bags with dead skin.

8. Your mouth is the most unsanitary part of your whole body. More than hundred million micro-creatures live there at any one time.

9. Feet sweat because there are about 250,000 pores on their soles that squirt a 60 millilitres of liquid each day.

10. At birth you have 350 bones in your body. You now have 206 bones. What happened to the rest? They fused to other bones to make larger bones.

11. Normal breathing sucks air into the nose at 6 km/h. A good sensory sniff is 32 km/h. A sneeze will shoot out of the nose at 160 km/h).

12. Your bladder can hold about 500 millilitres of urine comfortably.

13. Your nostrils take turns inhaling. You breathe through one nostril for three to four hours and then switch to the other one.

14. It is better to breathe through your nose than your mouth. Only air going through the nose is cleaned, warmed and moistened before it reaches your lungs.

15. Carrying your skin around can be a lot of work. The average adult's skin weighs about 3.2 kilograms.
