For those who believe in heaven: is it corporeal? What happens to bodies?

I don’t believe in the concept of heaven, so I don’t have any teachings that help me answer this question.

For those who believe in heaven, were you taught it is a real place where you have a post-death physical existence? Do you have a body in heaven, or is all virtual (spiritual)?

If you believe in a corporeal heaven, how does that work if the death was violent? For example, a person was decapitated and died. In heaven, is that person’s body all together again? The same would go for stabbings or gunshot wounds, or for that matter bad burns.

If you believe in a corporeal heaven, how old are you in heaven? For example, a person dies at age 80 after living a good and long life. Is that person 80 in heaven, or is that person 40? Or perhaps a child?

Finally, in your religious teachings, what is said about how people are dressed in heaven? Robes? Tuxedos? Street clothes? Nudity?

[Contemporary film offers no particular insight on this last question, but films are fictional anyway. Some films show heaven as people with long, flowing white robes. Several films show people in heaven as being formally dressed. ]

I am putting this in as a General question because I genuinely want to know what your teaching has been. I’m not going to question your belief.
