So I glance at my Kindle, which is off, and there's a picture of Jane Austen. She's a little plump, with curls around her face, and my mind says, "If I lived back then, I wouldn't be worried about dropping these extra pounds and fretting about my unfashionably curly hair !"
Things we concern ourselves with were no concern at all in other times, so I often think about the advantages of not living in the twenty-first century. Not wearing shoes might be good. Certainly times without bras were better. Days when older women were revered rather than ridiculed. Times when society was small enough that crime was minimal and eccentricities were handled with gentle understanding instead of governmental angst.
I'm not sure which other eras I'm best suited to, but I'm pretty sure I could cope, wherever.
I know what you're thinking: They had bugs. They died at forty. They had no concept of Facebook. Honestly, I see only one of those as a possible problem.
