What is the nature of Heaven?

[Machine_Elf]

I asked almost the same question ten year ago:

Christians: what is heaven like?

Christians, I’m told you all believe that heaven is what awaits (most of) you after your brain activity fades to zero. What do you believe heaven is like? Either in a general sense, or just subjectively for you? What will you be able to do? What will you want to do? How will you spend your time? Is it possible to do things there that would get you kicked out?
