It does, actually. Ice cream can put you at grave risk of brain freeze.

Good point! Then again, I don't think some flavors result in less brain freeze than others.

Even breathing has downsides.

True as well, every breath destroys lung cells.

If you want to be philosophical about it, consider this: If there weren’t pros and cons, you wouldn’t be making a choice at all.

This, however, I'm having a hard time to agree with. Come to think of it, I'm not even sure choice is something natural, but that will require some deeper investigation to ascertain. In a fictional natural state, when looking for a place to sleep, would a "family" really (have to) make a conscious choice between this cave and that one?

That's the most important question of our time. We have only a few decades to not only come up with that answer, but also with its rigorous implementation.

There seem to be many theories and strategies, either working within and outside the current system, but few seem ideal. Further worsened by the fact that the more ideal a solution seems, the more change it requires of regular folks, thus the more resistance it will face.

But then again, I'm sure once more people see the necessity of it, more discussions will happen, hopefully resulting in better contemporary strategies.
