I guess I'm a caffeine junkie and my cardiologist doesn't seem to have an issue with it.
I gave up all my vices in life except for caffeine and titty Tuesday!
I drink about 6 cups (large) black a day at home ...plus 8 restretto espresso shots from Starbucks. I don't ever seem to get a headache from it and I also drink iced tea all day.
My doctor says I'm in excellent shape . But I think that is because I do not eat sugar or flour.
I discovered coffee about the same time I discovered cigarettes. Quit the smokes years ago but still drink my two cups of perc'd a day. Any less and here comes the headache. Still would like to have a hot cup of mud and a Marlboro though, high living there.
Here's a form of coffee most people never see or even think about. The coffee "beans" you drink are roasted seeds from the fruit of coffee plant, called "cherries". They are harvested, wet milled, dried, and dry milled to create the "green bean" you see here. They are then roasted, ground and brewed. There's a lot of steps between the farm and your cup, and every step can make or break the quality.
My life is cars and coffee.
Kopi Luwak is wet processed by the digestive tract of a civet. A civet is closer to a mongoose than a monkey. No thanks.
