Most of us who travel, or use the notebook away from our desk or table tend to position the notebook on our laps (hence they are also referred to as "laptops"). Although the current generation of notebooks run both cooler and use less power, several studies have been published pointing out the dangers of positioning the notebook on your lap. While some point out the chance of developing testicular cancer (in men.....duh), most studies suggest notebooks can cause sterility by raising the temperature of their testes, as well as the unnatural posture most assume to use the notebook on their lap.
