Brown dwarf stars are cool. Both literally and figuratively; the temperature profile for cool brown dwarves runs somewhere between 225K and 600K. It's possible if not probable that there exist some brown dwarves at room temperature (≈300K or 80°F). With such a hospitable temperature, is it possible for humanoid life to survive around a brown dwarf? What if they lived within a pressurized station in the atmosphere?
I'm mostly concerned here about gravity, atmospheric pressure, and temperature, not so much about atmospheric composition.
I'm also not particularly concerned with the practicality of such a situation. Obviously the most practical way for life (as we understand it) to survive is on the surface of a rocky planet with atmosphere and water. Whether it's a good idea or not, these humanoids are forced to live here; I'm leaning toward some sort of forced emigration, scientific survey, or waypoint on a long but aborted journey.
