If you want to maximize your life expectation, you have to restrict yourself quite a lot.

And I think the goal of studies like this should not be to say "don't use it, it kills you" but rather to make us find a better alternative.

In terms of absolute physical harm, yes.

If you live with other people you probably need to convince them to do things differently too.

In my experience this can be very stressful and I wonder if the induced stress of even worse for ones health.

So? With studies like this, we can have less of this sort of death or at least minimize it and do things better, just like we have in the past.
