Coffee

A bad daily schedule could slowly kill you.  

Most adults can safely consume coffee. A condition called "caffeinism" with symptoms including anxiety or agitation may result from exceeding the recommended daily limit of 6 cups of coffee. People who regularly consume large amounts of coffee may need to consume more coffee to achieve the same results. Additionally, they can grow so "dependent" on coffee that stopping suddenly might cause them to experience withdrawal symptoms.

Unfiltered coffee consumption can raise blood levels of triglycerides, low-density lipoprotein (LDL), and total cholesterol. The possibility of having heart disease may rise as a result. These negative effects on cholesterol can be lessened by using coffee filters.

There is some worry that those with heart problems may not be able to safely consume more than five cups of coffee per day. However, multiple cups of coffee per day do not appear to raise the risk of developing heart disease in those without heart disease.
