Some interesting facts

Ancient Roman, Chinese and German societies often used urine as mouthwash.

This reminds me of a joke which my father used to tell us in Cantonese: 'Hei sun lah, oh liu long hau sai meen er' which means 'Wake up, urinate, rinse your mouth and wash your face'!

Zero is the only number that cannot be represented by Roman numerals... and

Google is actually the common name for a number with a million zeros.

Warner Communications paid $28 million for the copyright to the song Happy Birthday.

Just imagine how many of us could have infringed this copyright if it is still valid.

Soldiers do not march in step when going across bridges because they could set up a vibration which could be sufficient to knock the bridge down. Wonder what would happen if they march to 'Bridge of the River Kwai'.

Everything weighs one percent less at the equator.

This is some good news for those particular about their weight, especially some women. In a way, it depends a lot on how sensitive a person is to weight or height. For example, I remember when my sister-in-law was in UK as a student, she kept on measuring her height to prove to herself that she increased half an inch because of the western diet, especially dairy products.

And last but not least (I actually dislike this kind of pressure, similar to chain letters):

In 2011, July has 5 Fridays, 5 Saturdays, and 5 Sundays. This apparently happens once every 823 years! This is called 'money bags'. So send this on to 5 and money will arrive in 5 days. Based on Chinese Feng Shui, the one who does not pass this on will have money troubles for the rest of the year.

I did not forward, but posted this instead. Now what?
