I have often wondered if we are all children in heaven. I’ve always heard that while you’ll recognize your earthly spouse, you won’t have any romantic feelings for him/her. Personally, I think that it would be amazing to spend eternity as a child. You wake up everyday knowing that you are going to learn something new. There are no adult stresses or pressures (obviously, since it is Heaven).
You will be at your peak years. My guess around 30.
