What if you have you lived this life before,
and choose to live it again,
for forever?
The funny is that maybe we do not even know that it is repeating. Maybe all of this already happened many times. There are multiple films about this topic (time loops). For example 12:01 (1993) and Edge of Tomorrow (2014).
If I could choose, then I would repeat (or rather put into an infinite loop) only the pleasant parts of this life. Being constantly loved, giving love, and being constantly calm and relaxed, without any pain and without any other bad feeling/emotion is probably the closest thing to heaven.
