Interesting facts!

Got a mail full of facts!, I am posting excerpts of that mail, which interested me:-)
(with some comments from me within braces)

The roar that we hear when we place a seashell next to our ear is not the ocean, but rather the sound of blood surging through the veins in the ear. (then I am wondering how kushbu made it to sound like "I love you", oru vela "love" is injected in blood?)

The reason honey is so easy to digest is that it's already been digested by a bee.
(but our "honey"s are not so easy digests ;-))

It cost 7 million dollars to build the Titanic and 200 million to make a film about it (if we consider inflation rate then I think there is no big difference between the figures)

The sound you hear when you crack your knuckles is actually the sound of nitrogen gas bubbles bursting

Human hair and fingernails continue to grow after death (oh, thats the reason why ghosts have long hair and nails!!)

Every day 200 million couples make love, 400,000 babies are born, and 140,000 people die (looks like most of them are keeping it safe :-p)

Intelligent people have more zinc and copper in their hair (Oops, my hair is full of metals)

Do you know the names of the three wise monkeys? They are: Mizaru(See no evil), Mikazaru(Hear no evil), and Mazaru(Speak no evil)

Last but not the least:

If a statue in the park of a person on a horse has both front legs in the air, the person died in battle; if the horse has one front leg in the air, the person died as a result of wounds received in battle; if the horse has all four legs on the ground, the person died of natural cause.
