Stipulations:
- You cannot die and are immune to disease

Are you looking for ideas on things to do? When are you going back to 1945 and what part of the world would you be in?

You said you can’t change time or you cease to exist. What else are we supposed to do? You can’t exist and not change time.

But the catch is I dont know what will change time a lot or a little. If I get in an elevator and shit my pants in front of Utada Hikaru does she never write Simple & Clean? I simply cannot know, so with those rules I have to isolate.
