career path - Stay in academia or become professor without overworking, is it possible?

I am referring more to young scientists after the PhD than professors, although I am also wondering about people with a stable position.

I see many people overworking themselves, burning-out, being overworked and with pressure to work well, fast, and produce a lot (publications). I am discussing an average person who has completed a PhD that has all the skills for the job. Let's leave the top professors 5-10% of the field that are super-productive for whatever reason, those are exceptions. I also assume that there is passion for research, but that work balance is also important.

Is it possible to survive/remain in academia by working normal hours (8-9 hours per day) without working evenings, weekends, holidays, without feeling guilty about taking a 2-3 weeks vacation? I imagine to become professor would include many of the above sacrifices. Some professors (tenured) have told me they work 50-60-70 hours per week.

Is overworking basically the rule/working culture in academia? Is it unusual to reach/maintain a stable position in academia without regularly overworking?

Consider mentioning the cultural, country, institution type of your answer, as there are variations in different contexts.
