Things to do before I die

I really hope to have a hundred of these. It's just cool to actually try these things, y'know?

1. Climb Mt. Everest. Apparently, just knowing how to climb mountain won't do anything. I mean you need to prepare for like a year at least to get good enough to climb it. There's issues with oxygen intake and all that too because of the high altitude. And you need to know how to camp outdoors. It's apparently like $100K to climb the freaking thing.

2. Go to the Pitcairn Islands. Completely random, but I stumbled across these islands from reading a news article about milk but these islands are like ridiculously remote and apparently a place for "adventure tourists" (among historians, bird-watchers and the like). It just sounds cool. There's a boat that goes there like 3 times a year so I want to go. It's another expensive one though: http://www.pacific-expeditions.com/default.asp. ($6,400 to visit all four islands).

3. Visit the underwater resort in Fiji. http://www.poseidonresorts.com/poseidon_main.html It's called Poseidon Undersea Resort and it's $15,000. For 7 days. But there's all sorts of things that come with it and it oddly seems worth it.

4. See the aurora borealis. I just think it'd be really cool to see.

So this is it so far. Basically, I need to be rich when I'm old and gray. I wonder if I can just fly to the peak of Mt. Everest and take a bunch of pictures.... I suppose it's not the same as the actual experience (which would be really really cool....).

Now to actually save and do these things! :D

[edit]

Added a couple more:

5. Go to the Salt Flat in Salar de'Uyuni, Bolivia during the rainy season. I got this from here and I think it's really really cool. "The border between Heaven and Earth..."

6. See Gunkanjima (Hashima). Just seems kind of cool. Got it from 9gag and got more info from Wikipedia.  I might actually be able to go here this year. *hopefully* (Wanting to go to this island is partially inspired by the fact that there's a Gunkanjima in One Piece. Sad. I know. But I still want to go.)

7. Walk around the world. Again from 9gag. Basically if you go to either axis of the world, it can be done, right?

[update]
So, these trips sound cool, but I realized that I don't care to do half of these things. If I died before I did them, I wouldn't have any regrets.

I think the only one that really matters that I genuinely want to do is #4.
