What an interesting topic.
Well, this is more for the loved ones we leave behind i guess, but some ideas include:
* Freezing yourself - but this is seen as selfish or weird for the rest of the family. But if the whole family can get onboard, it'd be cool.
* Maybe bury myself on some high cliff watching the ocean and the stars all day and night. This is also nice but it might be seen as selfish by the family, unless they're also onboard for themselves.
* Cremating - i hate this. But if the family likes it, sure do it, i won't know anything anyway.
* Composting - kinda interesting but not sure how i feel about this, maybe you'll give life to a tree so maybe being buried next to a tree might be better as opposed to composting.
* Regular burial - most likely scenario - just MEH.
* Above ground burial - like the Egyptians in a tomb - i like this too and they do it in South America but just like freezing it's expensive and it's also seen as selfish.
And all of these options should be accompanied with some sort of party of music for the people.
That's all i got.
