Drinking tea won't really allow you to live forever, but that is certainly the first thought that popped into my head after reading the headline "Drinking tea linked to reduced risk of death." The article that accompanied the headline was about a recent Japanese study published in the Journal of the American Medical Association investigating the health benefits of drinking green tea. As other studies have shown numerous benefits, it was only natural to aim big and see exactly how beneficial the tea was, rather than continuing to only look at each possible factor individually. The study concluded that "those who drank five cups of green tea per day were 16 percent less likely to die from any cause during the 11-year study than those who drank less than one cup per day."
Does this mean that your life expectancy will increase if you drink more green tea? Not exactly, but it does mean that you can potentially decrease various risk factors that could contribute to health problems. In short, green tea isn't going to add any extra years to your life, but it could help to prevent those years from being cut short unnecessarily.
