That is not a good thing. Duh!
Whatever happened to Physical Education and, yes, Home Economics classes? it is pretty apparent that with most families where either both parents are working or one is absent that certain skills are not being passed on.
Exercise, nutrition and even personal finance should get a slot in the education process. The first two are critical for health and the third is critical in a much more complex financial world than 50 years ago. Yet we did provide such education back then. Maybe not so much personal finance, but the other two for sure.
Lack of education in such matters is costing us a lot of money and even affects national security.
