Eight Random Facts

This is a meme from Clare Dudman.

Here are the rules:

1. I have to post these rules before I give you the facts.
2. Tagees should write a blogpost of eight random facts about themselves.
3. Enough rules already...

Here are the facts:

(1) I am one of the seven out of ten people who cross their left arm over their right.

(2) There are more bacteria in my mouth than the human population of the United States and Canada combined.

(3) There is enough iron in my body to make a small nail.

(4) My eyes can detect more than 10,000,000 different colours.

(5) My heart is twice the size of my fist.

(6) I have enough carbon in my body to fill 9000 pencils.

(7) I, like other humans, find it impossible to tickle myself.

(8) If I died today, my brain would still be sending out electric wave signals tomorrow.
