Usually for living in space, a spacesuit is needed. You will pass out after about 15 seconds after removing spacesuit and 90 seconds after exposure, you will die from asphyxiation. The space is so cold. We may freeze there. Any exposed liquid on your body will begin to vaporize. So the surfaces of your tongue and eyes will boil. Also the lack of air in lungs, blood will stop sending oxygen to your brain.
