There is no way 8fl oz of brewed coffee contains 100 to 200mg of caffeine the average cup of black coffee contains about 50 to 60 mg of caffeine depending on the brand.

I think your point of view creates your reality. If you think coffee has great benefits, it will be good for you. If you believe it's bad, it will have negative effects on your body
