Within your lifetime or beyond. Not just personally, as in “yes, back then I had all my teeth,” but at least some large or small aspect in which a typical person transported back in time would say, “why yes, this is better than what I’m used to in the twenty-first century.”
Small things: I’m not an expert, but I understand that furniture was much more durable and of better quality, often with types of wood that you can’t get anymore.
Bigger things: it may not be a popular opinion, but I think more durable marriages, and not so many fatherless kids around, was one thing that may have partly counterbalanced all the other things that sucked in societies of the past. Maybe not necessarily in terms of individually happy love stories, but a bit more social cohesion on a larger scale at any rate.
