TV junkies...

A study has apparently shown that young children who watch too much TV are likely to suffer from a whole load of negative consequences later in life.

Interesting, and I don't doubt the studies findings, but I do think this could be an interesting example of "correlation does not cause causation". Just because there is a relationship, it doesn't mean that toddlers watching lots of TV causes them to have higher BMI's, poorer performance at school, etc.

It could be that watching lots of television may also be one of the outcomes of some other causal factor. What might cause a child to watch lots of TV, be overweight and do poorly at school? Now that would be an interesting study...
