Boy, this was long. I'll just include the ones I've commented on:

03. Climbed a mountain - yep, every year
04. Taken a Ferrari for a test drive - no license yet
09. Hugged a tree - I had a favourite tree when I was about 11, and was very sad when the landowner cut it down
12. Watched a lightning storm at sea - from a beach in Thailand - amazing
13. Stayed up all night long and saw the sun rise - um, every Christmas party
14. Seen the Northern Lights - not too hard where I am, most recently 2 weeks ago
31. Screamed as loudly as you possibly can - during giving birth counts, right?
33. Seen a total eclipse - yes, and it was quite spooky
36. Danced like a fool and not cared who was looking - um, every Christmas party
38. Actually felt happy about your life, even for just a moment - luckily, lots of times. Just not at the moment.
41. Taken care of someone who was drunk. I once had to babysit a teacher on a university trip, he was an alcoholic, got wasted and passed out. Very sad, not least his reaction when he realized what had happened.
48. Gone rock climbing - 2 or 3 times a week
50. Gone sky diving - my hell-i-can-do-what-i-want-period
76. Gone without food for 5 days - I was an apprentice jockey (see above) when I was 16-19, and went pretty much without food for a week to make the weight for a specific race. never ever again.
102. Sang loudly in the car, and didn’t stop when you knew someone was looking - ha, I do this on my bike frequently
108. Piloted an airplane - yes! got to try out a set of double controls once
116. Fired a rifle, shotgun, or pistol - yes, but only at tin cans pretending to be polar bears
135. Selected one “important” author who you missed in school, and read - I once took Miltons Paradise Lost along as my only reading material for a two-month long hiking trip. Nearly went insane.
