People were naturally much thinner then because of the food and the exercise. Kids rode their bikes or walked. People were outdoors more often.

Look at old footage from the 1970s in the US - it's like a different world. Everyone looks much healthier (beyond some weird styles) and much thinner.

There was the hyper-feminine look, but there was also the natural look. My whole school group went for the natural look, but even the cheerleaders with big hair and way too much mascara often wore flannels and jeans.

I miss that time. The music was much better and people just seemed to have more fun. We hung out and talked on the phone a little, but mostly hung out. Now these kids spend all their time on their phones comparing genders. The internet has, in some ways, been absolutely disastrous.
