Ultimately, no. I think I was meant to be in this time.
Yes, there are other time periods that were likely more fun, more comfortable, more comfy, more interesting. Hell, I'd bet there's one that you could even call perfect. But, given the chance to be reborn in one of those, I wouldn't take it. Although, I wouldn't mind going back to the time before the evolution of life. It must have been beautiful. I wouldn't mind dying in a place like that.
