I came across this article today which claims that according to research, 5 to 8 times more children today have depression and anxiety. Than those going all the way back to the 1950's.
They feel this is due to the lack of control kids have today as they are not able to play freely anymore, and have more test score pressure put on them. I found it an interesting read. Hopefully the link works.
