I was taught that while separated from our bodies we would long for them and the resurrection.
Also, any habits or addictions followed us to the spirit world. Addicted to cigarettes? You would still be addicted as a spirit but would be tortured that you didn't have a body in which to go and light one up.
WTF is the big deal with having a body anyway. There is a mojor part of the world that is struggling with birth defects, starvation, torture, and pain in this "gift" of a body every single day. I have cancer and tumors in my "gift". Everyone suffers sooner or later and it is sometimes through their body.
