It seems to me both.

As Jack often notes when people in our age group were kids there was 'THE fat kid' at school. Now it seems the not fat kid is the oddity.

We often ate potato chips and fries, but even mcdonalds fries were made in animal fat not seed oil. The rest of our food was similarly 'better than now'.

Also, if we wanted to play video games, we had to at LEAST walk down to the pizza shop, or all the way to the arcade, which was quite a hike. So if we 'played video games all day' we still got a LOT of exercise.
