seeker - really!
Actually coke/cola is totally toxic. If I was to go on and do a Masters, exploring the relationship between kiddies drinking coke & teenage drug/food addiction would be a fab place to start.
A quick google on the subject of coke/cola will open your eyes as to the damage it can do and to it's addictive nature. For a start:
"The active ingredient in Coke is phosphoric acid. Its Ph is 2.8. It will dissolve a nail in about 4 days."
My younger brother drank coke from about age 6 - he quickly became addicted and it amazed & shocked me how his parents did nothing about it. He ended up very overweight, drinking 2 + litres a day. His consumption had a huge effect on his childhood & teenage years both behaviourally and by making him a fat kid.
Now 21, still carrying all the COKE fat, he now no longer drinks coke -he replaced it with beer a couple of years back & drinks like a fish.
