Hi Thaddeush13,
Biases - " lacking a neutral viewpoint, or not having an open mind".
The potential biases that could hapen in this experiment are different intakes or types of coffee. For Example, Cold, Hot, Caramel. And each as a different size. Sugar intake is also another problem here.
Life expectancy for smokers is at least 10 years shorter than that of non-smokers. Quitting smoking before the age of 40 reduces the risk of dying from smoking-related disease by about 90%.
