because it is an individual award
they are kept less so as to make them more sharp-edged, to increase the effect of force. so less area makes more pressure.
They work by making the head a bit more aerodynamic, making it slip easier through the air. With less wind resistance you get the same speed at less effort, or more speed at the same effort as if you didn't wear a helmet. And some of them are tested to the same level of impact protection as regular helmets,which can reduce the risk of injury in case of a crash or a fall.
Yes. Go to Stanford on-line for more information on the their master degree programs.

Yes bike helmets are necessary for a short trip, for your safety. For more information go to www.rei.com/category/4500003_Bike+Helmets, www.dickssportinggoods.com Home How To
SNELL is an addition safety rating for helmets. The SNELL Foundation certification is more stringent than DOT certification.
Tiger Woods took more than one course at Stanford University. He majored in economics and was sent to Stanford on a golf scholarship.
The helmets were leftover from World War 1. More had to be made as more people joined the home guard and air raid wardens.
Bicycle riders are expected to fall less often, but with more force than skateboarders. So bicycle helmets are made to soak up more force, and then be replaced after a bad fall. Skateboard helmets are made to soak up less force, but to remain useful even after several falls. Bicycle helmets are also generally made to allow more airflow, to keep the rider's head cooler during hard riding.
snow mobile helmets are more insulated than motorbike helmet,snowmobile helmet has double lense,face shields in snow mobile helmets are anti fogging,snow mobile helmet have enough room for air circulation for anti fogging,motorcycle helmets are hard
The most used, especially in younger leauges, are Schutt and Ridell helmets. In the older leagues you also start to see a more modern designed helmets that is a Revolution helmet
Absolutely yes. Think of all the crashes you see at the race track with drivers that have helmets and walk away from them. Granted there are a lot more modifications done to the race vehicles also, but I believe you would have less chance of a fatal accident if you included a helmet with a lap/shoulder harness also.
