Similar to humans, cancer is the leading cause of death among older cats. It is caused by uncontrolled cell growth, and affects a wide range of cell types and organs in the body. Feline cancer initially manifests as a lump or bump on any parts of the body.
Adaptive headlights make driving at night or under low-light conditions safer, by adjusting the car's headlights to curves in the road. Rather than pointing directly at the space in front of the vehicle, they adjust to illuminate the area that the car will occupy next.
Adaptive headlights aren't yet standard equipment on most cars. In fact, only a few companies even offer them as options. BMW offers optional adaptive headlights on all models, while 335, 535, 7-series and M-series include them as standard equipment. Renault offers them as an option on some models, and the 2006 Volkswagen Passat includes them in the optional Luxury Package.
