yes, you read right! it is completely false. i've found that in general, to remain healthy, we do need to take in the water that we lost through exertions, sweat and other bodily functions. BUT water intake varies from person to person. factors includes age, weight, activity level and the climate where the person lives. the 8 glasses per day is a thumb of rule really and interestingly, it doesn't have to be just plain water.
and to add to this myth, there has been a general thought that drinking coffee, milk, tea, soda or other drinks makes you dehydrate more. a research on this discovered that there were no differences at all. one glass of any of these drinks amounts to about the same hydrating fluids as a glass of water. only drinks with alcohol makes you dehydrate but even then, one needs to drink a lot of it to have noticeable difference, doctors say.
so if you have kidneys the size of a peanut (like myself), the best hydrating advice is "drink if you're feeling thirsty. and you don't have to drink when you're not, unless you want to."
this myth started with an email being circulated:
I feel that the following is information that any one who uses a microwave oven to heat water should be made aware of. About five days ago my 26-year old son decided to have a cup of instant coffee. He took a cup of water and put it in the microwave to heat it up (something that he had done numerous times before). I am not sure how long he set the timer for but he told me he wanted to bring the water to a boil. When the timer shut the oven off, he removed the cup from the oven. As he looked into the cup he noted that the water was not boiling but instantly the water in the cup "blew up" into his face. The cup remained intact until he threw it out of his hand but all the water had flew out into his face due to the buildup of energy. His whole face is blistered and he has 1st and 2nd degree burns to his face which may leave scarring. He also may have lost partial sight in his left eye.
While at the hospital, the doctor who was attending to him stated that this a fairly common occurrence and water (alone) should never be heated in a microwave oven. If water is heated in this manner, something should be placed in the cup to diffuse the energy such as a wooden stir stick, tea bag, etc. It is however a much safer choice to boil the water in a tea kettle. Please pass this information on to friends and family.
many thought this email was just a typical scare-o-gram, it turned out to be true. conditions need to be perfect and you might not even get to see the phenomenon. but if you get it just right, you'll get this:if you are 'lucky' to see that, chances you'll get hit in the face is very very rare.
TRUE and FALSE
to be honest, i found a lot of answers and explanation to this myth. some proved it to be true by experimentation and videoed his findings and some explained scientifically with physics.
Soda Can Lid Tapping Urban Legend - Awesome video clips here
a website i stumbled upon gave me different results with different beverages, time length of tapping and the resulted foaming. click here to find the results in more detail. her final conclusion?
Tapping on a soda can will not decrease the liklihood that it will foam over on you when opened. It will, however, give you something to do while you wait for the contents to calm down. Generally speaking, one minute is a sufficient amount of time to wait before opening a shaken soda can. Of course, these tests were all done in Portland, Oregon and the majority of the soda was cold. Results at other altitudes with other temperatures of soda are unknown.
very amusing.. the best conclusion of this myth is just let can rest on a table for a few minutes before opening it.
i hope that was a good read!

Water is actually good for your skin, it "washes" away toxics in your body and it helps you maintain a healthy body.
Sodas DO hydrate you, but it contains harmful chemicals that are not necessarily healthy for ones body.
Although TOO much water can be harmful as well. :P
I don't know what I'm saying. heheh. hey sham :)
The soda videovlip looks a little bit "setup". It is not continuous, I mean, they zoomed in on the first can, then replaced it with a new one and went back to the previous scene.
mash: i forgot to mention that. yes, it is true that drinking water is healthier for the skin. i was just trying to say, we don't have to drink constantly to hydrate ourselves. yeah. i heard that drinking a lot of water can be dangerous.. hmm.. i might research on that..
utwou: hmmm.. interesting observation there. i didn't notice that.
