A mid-sized jet, the 757 isnât nearly the size of a 747 or 777, but thanks to a nasty aerodynamic quirk it produces an outsized wake that, according to one study, is the most powerful of any airplane.

Causes: Colorectal cancer: All kinds of cancer occur when cell division, normally a very highly regulated process, gets out of control. While environmental factors can certainly contribute to a person's risk of cancer (e.g. smoking, diet, and exercise), most cancers have a genetic basis too.
Each year, more than 49,000 people die from colorectal cancer. Colorectal cancer is the second leading cause of death due to cancer for men and women combined. It accounts for 8% of the cancer deaths among men and 9% of the cancer deaths among women. Lung cancer is the first, it kills over 100,000 people per year.
