I can only speak for myself as I personally know no dead and nobody is getting back to me on the Ouija board, but I hold deep suspicion that I would not be happy as a spirit without a body. I certainly wouldn't be happy in a body that a) wouldn't die or b) was falling apart all around me. This is not meant to imply that I am currently happy for I'm not. I can't imagine this ennui being placated by becoming a restless spirit.
The spirit is the quintessence of what it means to have lived at all. I am not my body, I am only my mind. Even believing this, I do not enjoy the idea that the spirit might live on after the body has fallen.
Leave it to us to take the morbid road less traveled upon first impression. If you knew that you were to die tomorrow, how would you spend today?
