More on Puzzled

The mystery of the tile puzzles being removed from the shelves at Wal Mart has been solved. I discovered today that the puzzles have reappeared on the shelves. If the manager was correct when he informed me that the product was being tested, I can now assume that the puzzles are safe for children--perhaps. This news is timely since an article in Science Daily Digest titled Even Very Low Levels of Lead Causes Brain Damage in Children, profiling a Cornell study, suggests that the established acceptable lead level in products may be too high, and children might be in danger. The danger might manifest in lower IQ scores and other problems.
