Atleast half of the world population is connected to the internet and most of us utilize laptops but this can be somehow risky to your life if you don't take precautions when using the device especially those units from Dell, HP,Lenovo and other brands they can be so much dangerous to your health either long term eyes side effect or other long heal disease. Apple's production is far more different from those other brands because its ventilation system isn't underneath the laptop so for it the risks where minimized but still its more advised to use a office table when doing work with laptops. The heat that comes out the gadget fans during cooling system can cause the same damage as a heated up can radiator coolant. Stay warned and stay safe!!!
