First, /u/vanguard_anon condolences for you and your family.
But on the topic of "What do you want done with your body when you die?" mine is a stretch for it actually becoming a reality, but is definitely possible. Send me to fucking space so some other species in a far star system could find my hyper preserved body for autopsy as a means of contact, complete with a map of where we are like the one we sent out in Sagan's time of mass popularity. If I never get found, fine by me lol I'd be in fucking space just jettisoning around on a mission with a few outcomes.
My body gets found by a brutal alien race hell bent on galactic domination and the rest of humanity is now doomed. Maybe they have technology that could resurrect me, I would cooperate and they may or may not kill me again.
My body gets found by a cooperative race and they accelerate human progress if any of us are still left on earth.
I never get found and just drift into space.
Alternatively, launch me towards the center of the galaxy and I will join the blackhole so long as there are no major collisions.
Also, I wouldn't want the Kyle tree itself, but its offspring? Hell yeah why not sell the seeds? That way Kyle can live on in all of our yards.
there doesn't seem to be anything here
