For us sedentary types, perspiration is usually a problem. Seriously, the average desk jockey is libel to sweat from stressful physical activities like typing and chewing. That's why you need a Wi-Fi fan.
In all seriousness, if chewing makes you sweat, chances are the act of fanning yourself is libel to compound the problem (you may also want to hit the gym). But hey, it's a fan...shaped like a Wi-Fi icon. Pricing and availability on the "Wave Wireless Air Activator" have not been announced. [Atypyk]
