Encha seus pulmões em fontes de ar:
For the filling stations are the primary venue for social conversation, the places from which we draw emotional sustenance as well as physical. We all keep spare sets of full lungs in our homes, but when one is alone, the act of opening one’s chest and replacing one’s lungs can seem little better than a chore. In the company of others, however, it becomes a communal activity, a shared pleasure.
E o fim do universo:
Perhaps a few of us, in the days before we cease moving, will be able to connect our cerebral regulators directly to the dispensers in the filling stations, in effect replacing our lungs with the mighty lung of the world. If so, those few will be able to remain conscious right up to the final moments before all pressure is equalized. The last bit of air pressure left in our universe will be expended driving a person’s conscious thought.
And then, our universe will be in a state of absolute equilibrium. All life and thought will cease, and with them, time itself.
