OK, go to 'Start', 'All Programs' and look for the 'Common Sense' Application.
R U the only male doing this?
Has this been happening for enough years for a wave of fertility issues confined to male laptop users with WiFi to be detected?
If the answers to the above are not enough, consider;
In a recent experiment, people who claimed to be extra sensitive to mobile phone masts were found to be unable to tell whether they were on or off, but if they thought they were on they still felt ill and manifested physiological symptoms.
Not one cluster of illness related to mobile phone masts has been proven to any satisfactory level or scientific rigour.
The best longitiudinal (over time) studies to date have not found any linkage between mobile phone use and and health issues in normal usage. 'Continual' usage for ten years or more might have a very small chance of giving you a brain tumour.
Workers in ocupations that exposed them to high RF radiation in the past 50 years have provided no evidence of increased occupational health risks, apart from one or two people who accidentally cooked themselves in freak accidents.
WiFi access points and cards et. al use power levels at most 10% as high as the most powerful modern cell phones, more usually around 2%.
Basically, you are more at risk from tight jeans or underwear. and the heat of a laptop's other innards raising the temperature of your balls to one unsuited to spermatogensis, than the minute thermal load of a WFi connection, or any other RF risks of the same.
