Coffee drinking linked to longer life

The fact that I'm a minority and that fast metabolizers might actually benefit from caffeine says to me that going just on that article might not be a good idea.

A majority of people might benefit from caffeine, while a minority might have really dire consequences.

/edit this is all preliminary research so add more weight to "might" that I use here.

Science is about trying to explain the world, not looking for random facts.

We learn nothing of substance about coffee, health or anything else from this article. Yet it has the appearance of being scientific, for example, it mentions antioxidants.

It wouldn't be fair to label it pseudoscience however it does share some of the features.

People are starting to learn by now that correlation doesn't imply causation, but they still think it is suggestive of causation, or makes causation more probable, or something like that.

To try to dispel that: the fact that coffee drinking correlates positively with life expectancy is logically consistent with coffee acting to reduce lifespan. More importantly, knowing causes is not very helpful since pretty much everything causes pretty much everything else.

What is useful is solving problems and trying to explain the world. That's what people like Newton, Darwin and Einstein were doing.

FWIW my guess is that drinking coffee causes people to eat less food which might indeed result in greater health, though this doesn't seem like a fruitful line of enquiry.
