If Mormons have it right, then when we die 1) We'll get perfect bodies that will never die again, 2) Earth will still be around for us to appreciate, and 3) Fun will not end. Wholesome recreational activities are part of maintaining a successful marriage, right? And we believe in eternal marriage. Well here's my list of epic date ideas for eternity, babe. 

1. Squirrel suit skydiving. Turn off immortal antigravity superpowers if necessary so I can enjoy this the old-school way.
2. Marathon skydive (26.2 miles up. It's a super-sonic freefall from the edge of space!)
3. Run on water
4. Go sailing in a hurricane
5. Get struck by lightening on purpose. Like... bait the lightening. =D
6. Make dragons. Then ride them. 
7. Play dinosaurs with real dinosaurs
8. Climb Mt Everest.
9. Solar surf the edge of a nebula (view link from :40)
10. Shoot heavy metals into a star to trigger core collapse. Also play with pair-instability supernovas.
11. Scuba dive without air tanks
12. Go over Niagara Falls in a wooden barrel
13. Design sunsets
14. Grow enchanted fairy gardens we can wander and get lost in
15. Weave a dress of spider silk, bioluminescent algae, and arachnocampa luminosa (glow worm) threads
16. Just hold hands with you. 'Cause I don't think I'll ever get tired of that either. 
17. Take all the time needed to master a symphony of instruments. Finally compose the music that haunts my head
18. Watch reruns of our lives. Specifically look for moments when I pranked people but didn't get to see their face.
19. Snuggle up next to a tiger for a nap
20. Learn what all those poisonous mushrooms really taste like
21. Solo climb the Yosemite Half Dome
