If you take 4, is 6 still dangerous?

How is 3 useless? If you want to do a profession or skillful activity you just need to warm up a bit and you’ll excel. You can write amazing stories, be a 5 star chef, learn any language and make option 1 redundant, you can do anything a single person can accomplish.

I’d say 3&4 are the prime combo. Succeed at whatever you want to do and be in perfect health the whole time

2: This is genuinely a curse; You will remember every little thing that happens to you and it will haunt you forevermore.

Wouldn't perfect memory recall just let you recall memories, not necessarily be forced to recall them? Whether or not you chose to do it or it haunts you seems more like a matter of mental health...

6. When you die, you remain unconscious indefinitely. The outside universe remains paused as your protons decay. Unfathomable amounts of time pass only for your body. Eventually, a Boltzmann brain that matches you arises. Time unpauses and the energy this microcosm contained is released into your neighborhood.

6 very much depends on interpretation. I think yours is overly negative - the net benefits are considerable! So much so that I picked 4&6 even before I noticed that 4 averts 6's issue.
