On Sunday nights at 10pm, the Discovery Channel began airing a show called Head Games- the Seeing is Believing episode covered how our brains work when we're on the cell phone. (very scary when you think about the number of people who talk & drive) It's a very interesting & informative show. You should check it out sometime ;)
Next question overall
Why women's boobs get bigger after 40.and why can't we loose weight easily ??
