UHHH... my gosh, I feel mean to mention it, but your pictures tell a lot about weight problems in the U.S., you are a nice exception, but there are a lot of young and supposed to be healthy people in the background who should not look like they do. I do not want to offend anyone and I do not want to make fun of the "fat kids", but i have been working in an health information campaign here and visited around 250 schools doing this and during this time I have seen kids like this at every third or fourth school, not that many in that tight space...
Wow... Is it me or does this seem a little out of place.
Where your observation may be true this thread is no place to point out complete strangers flaws. It could just be health problems that make people the way they are. Not all people gain weight due to just eating.
