Can’t sleep, probably too much coffee.
But coffee is good for me, according to a study. I’m less likely to have a stroke, and the more I drink the smarter I get.
I want to believe that coffee drinking promotes health. More likely, the women who feel run down and sick aren’t up for a cup of coffee. The coffee drinkers weed out as those old ladies who have strong stomachs and can still find the bean grinder and have the ambition to grind the beans. It’s so much easier to drop a tea bag into a cup of microwaved water. Yuck.
But there are those who have just stopped caring. And they have stopped drinking coffee. They are too debilitated to brew the staff of life, and so drop out of the coffee drinking group. Only the strongest keep percolating.
Causation vs correlation- it’ll get you every time.
