If you stretched out all the DNA in a human body, it would measure about twice the diameter of the solar system.
27. The largest organ in the human body besides skin is the liver, which weighs 3.5 pounds (1.6kg).
28. The human body produces trace amounts of dimethyltryptamine (DMT) which has been called "The most powerful hallucinogen known to man and science."
29. An average 70 kg (150 lb) human adult has approximately 7×10^27 atoms and contains at least detectable traces of 60 chemical elements, some of which are metals that only form during massive celestial explosions like Supernova.

33. You develop a fever when you're ill because the kind of bacteria and viruses that infect us have evolved over millions of years to work best at the normal human body temperature of 37°C (98.6°F). So human body raises the temperature to kill them.
34. Nearly 25% of all the bones in a human body are located in the feet.
35. The human body literally glows, emitting a visible light in extremely small quantities at levels that rise and fall with the day. Past research has shown that the body emits visible light, 1,000 times less intense than the levels to which our naked eyes are sensitive.
