Solitude: sweet absence of faces...

As unlikely as it may be, if a person were to be born blind and deaf and mute, without the ability to feel anything, but could breath and be fed through a tube, would they really be alive? What the hell would that be like? Could the person have thoughts? And what would be even more interesting to think about, what if someone cured that person of all their problems and the person could see, hear, and make sounds, could finally feel things, but only for one day, after which the person died?
