title_body: Disadvantages of coffee?
upvoted_answer: The only disadvantage that I see from drinking coffee is that you don't have the time to drink tea!
  
  At the age if 68, I average 6-8 cups of coffee daily,  and have done so for the past 50 years or so. My current job,  I got bored  with retirement,  now averages 35 - 40 hours per week involving continuously standing,  bending,  stretching,  and walking an average of 10 miles a day pushing loads up to 300lbs at a time.
  
  Oh,  the last cup if coffee is right before bed.
  
  If your family keeps nagging you,  take away their soft drinks and cigarettes,  then let them REALLY complain.
