The study was a poll where people were asked if they drink coffee or not and if they drink then what type of coffee did they drink. Statistics now show that people that lived longer also drink coffee. Although there is no clear evidence to sustain the theory that coffee actual makes you live longer the numbers give credibility to this theory.
Believe it or not one thing is for sure: You can drink your coffee in the morning without the worry that it might have some bad effects on your health.
