Coffee is dangerous, Again.

Do we really need another poor study on how coffee can harm us? All the previous studies, on further follow-up showed such studies were flawed. Coffee consumption is almost universal, the use of recall is inneffective, biological plausability is minimal, and controlling for varied use while mathematically possible does not work in practice. Of course it makes headlines for activists who want something to shout about, and wastes resources in replication with better studies which will fail to show any effect.
