I don't think that can be generalized. I hate being inactive and feel worse when I am. I don't need to constantly lift weights or run, but I have a desire to be more active than what is "needed" in the context of day to day living. As technology progresses, our activity demands lesson.

I don't think we can compare activity levels with other animals given the vast differences in lifestyles (both labor and liesure), diet and access to food, shelter (e.g. preparation for hybernation), and so many other factors.
