Up to 25 Cups a Day

That is an impressive number.  In a new study, subjects were sorted into three bins: less than 1, 1 to 3, and 3 up to 25, and arterial stiffening was tested for each group.  No correlations were found between level of coffee consumption and arterial problems.  Good, I'll take it, with a triple espresso on the side.  link to article  RTWT, it's short and has so-bad-it's-good humor smuggled in.

Three observations: (1) 25 cups upper limit?  I'm guessing they had to cut things off there due to the quantum properties of people who consume more than 25 cups per day.  I mean, it's hard to measure somebody's arterial stiffness when you can't localize the person's limbs due to the jitters.  (2) These levels of coffee consumption may not stiffen the arteries, but the study did not seem to address stiffening of the eyelids.  (3) Overall, it's good news.
