I have been looking through old photo albums recently and noticed that pre 1980 everyone in the photos were thin. And not starving themselves thin...just slim. And since 1980 it seems that with each passing year people in the photos started getting heavier (especially me). And now today it seems the whole western world is being overtaken by obesity. What has led to this social change? Food availability?, fast food joints? Alien bacteria leading to obesity? As kids we ate all kinds of junky food but we were thin as rakes. I feel bad for the kids of today. What happened post 1980?
