What the average human body contains

The average human body contains enough potassium to fire a toy cannon, phosphorus to make 2,200 match heads, carbon to make 900 pencils, fat to make 7 bars of soap or 75 candles, iron (0.01% of body mass) to make a 7.5 cm nail, water (70% of your body) to fill a ten-gallon tank, and enough sulphur to kill all fleas on an average dog.

Sulphur is necessary for the production of keratin, a protein that promotes healthy hair and skin.

Of the 118 known elements, 24 are found in the human body, making up about 5% of your body – half of that is calcium. A combination of elements make up minerals.

The most important part of a human, though, is having a healthy attitude.
