These things I have learnt recently during a series of brain enhancement games on my WM5 phone.

1. A whale's heart beats only 9 times a minute.
2. An octopus has rectangular pupils.
3. Snakes can sleep about 3 years running without any food.
4. There is a theory that the origins of the term 'honeymoon' date back to the time of Ancient Babylon. In Babylonian culture, the father of the bride would provide his son in law with all the mead (a honey based drink) he could drink during the first month of marriage. And because the calendar was lunar based, this period was called moon. It was believed that drinking mead would increase the likelihood of producing a son.
5. The material with the highest thermal conductivity is not a metal like silver or copper, but diamond (about 6 times that of silver). If someone were to make a diamond tea-spoon, they would be burnt just after it was put in hot tea.
6. The cigarette lighter was invented before the friction match. Early matches were so dangerous, there was enough phosphorus in one packet to kill a person.
7.The most common element on Earth is oxygen, mainly because of the SiO2 in the earth's crust.
8.In a group of 40 people the chances of two people sharing a birthday is around 90%.
9.Hippos kill more people each year than crocodiles.
10. If a line of all the 18 year old men from China walked past you, it would take forever to end, as people would be added to the end faster than they could pass you.

That's it for now, my brain hurts.
