I'm a gamer and have too many fizzy drinks and not enough exercise, am I basically dead ?

If you think you need to go to the doctors, go. It will definitely help you mentally at least, try cut down on the fizzy drinks and energy drinks, you know too many are bad for your health! please try go to the doctors, if your mum brushes it off go alone or if you want some support try talking to someone you trust and ask them to come with you!

Cameron this is a well known side affect caused by energy drinks in young people under 18 years (from studies) and these disruptions can be bad for cardiac health. Palpitations happen even with small doses (such as one can daily) in kids of 12, so cut right down, drink some water when you're thirsty and you should improve markedly. Good to have this sort of scare young so that you can grow well. The fizzy drinks also usually contain phosphoric acid which dissolves the enamel on your teeth, as well as undermining the integrity of your bones by essentially 'dissolving' the growing bone matrix so leading to osteoporosis (yes the old ladies disease). Please stop buying into the commercialism of water by supporting the manufacturers of the fancy fizz. They're making too much money destroying our health! Water is the way forward!!!
