An observation: old school "average", 20 years ago and today. I´m in college and I have noticed that there seems to be an increasing number of fats, while at the same time a substantial percentage of people are very fit, into the gym lifestyle. This may depend on your country, I think in general in European countries is not as noticiable (but still), but in some countries seems that among the people I know there are many small fats and then really fit/muscular people, but less and less average "slim" people  20 years ago 90% of the people you see walking by the streets would have been categorized just as "average". Today they are the uncommon ones.  Your experiences?
