What's causing our kids to become autistic, fat, near-sighted and sleep deprived?

TV!  This latest study found that watching TV lowers melatonin levels which can create all sorts of nasty side effects in children.  This study (as others) linked TV watching in kids to:

• autism
• obesity
• trouble sleeping
• eye problems
• lower melatonin levels
• early puberty

In adults, "the risk of developing Alzheimer's disease increases with each extra daily hour of television viewing among people aged 20 to 60."

Watching TV must give people immense pleasure ... otherwise I can't imagine why they would expose themselves and their kids to so much of it. We spend nine months of pregnancy trying to eat right, drink no alcohol, get all sorts of prenatal tests and then we plop our toddlers down in front of another round of SpongeBob or Thomas the Tank Engine without a second thought.
