Most likely you’ll just another cadaver for a medical student to study. That’s not a bad thing just that chances are you’re not going to be a contribution to some major scientific research.
I have also seen firsthand the other things that happen to donated corpses -- the pile of skeletonized legs in the corner connecting dust, for example -- and I can safely say I will never ever ever donate my body in this state.
So maybe it’s not a good idea.
