Hair Raising!

Blondes generally have more hairs on their head than others (150000 compared with 110000, 100000 and 90000 for brown, black and red-haired people respectively).

Where's the best place to do your maths homework?

At the multiplication table.

Weights and Measures

A pound of feathers weighs the same as a pound of lead.

However, a pound of gold weighs less than a pound of feathers, because gold is measured using troy weight and there are only 12 troy ounces in a troy pound (just over 13 standard ounces), rather than the usual 16.

What is a bird's favourite branch of Mathematics?

Owl-gebra.

A Puzzle

Do the following:

think of a number between 2 and 10

multiply it by 9

add the two digits of your answer together

subtract 5

Replace the number you now have with a letter using the rule that 1 is A, 2 is B, etc.

Think of a country in Europe beginning with your letter.

Think of an animal (not a bird or a fish) beginning with the second letter of your country.

Think of the colour of your animal.

You're pretty sure to be thinking of a grey elephant from Denmark.

Time

The Earth is between 4.5 and 4.8 billion years old.

Heartbeats

A human heart beats around 100 000 times a day, give or take a few thousand.

What Are The Chances?

If you put 40 people in a room, leave the room, and ask a friend to select one hair on one of the 40 people's heads, then come back into the room and try to guess which specific hair has been selected...

...your chance of guessing the correct hair is about the same as your chance of winning the main prize in the UK Lottery.

Nature

There are more trees on Earth than stars in our galaxy.
