These aren't controlled experiments so how could they possibly rule out selection bias affecting the coffee drinking cohort?

Maybe healthier people can handle high coffee consumption better for example, and maybe they are more likely to be in sociable and professional settings, both of which are associated with better health.

That's a good point. Four cups of coffee would put me in the hospital.

A "cup" is almost certainly less than an actual normal serving these days.

The risk of death is 100%, coffee or no coffee.

Not true. I've lived over 20 years and have had 0 deaths during this time. [1]

If you plot my number of deaths and extrapolate you can clearly see that I'll never die. [2]

So with coffee, your chance of death is now negative! :-)

Death from what? I'm assuming some sort of heart related danger based on where and who was doing the research, but this doesn't tell me anything otherwise.
