i went shopping today. i noticed both the walmart and the lowes store affecting my thinking. i think it was a combination of some chemicals in the air conditioning or store and the florescent lighting. it made me much more drowsy and when i walked into the hardware store i had forgotten what i was looking for. the same chemical was in the hardware store that was in the walmart store. i then left that store buying nothing and went to a smaller local hardware store where i found what i needed and they didn't have the chemical smell there.
