Daredevil sports are also becoming popular. Young people especially are increasingly willing to risk life and limb while mountain biking, backcountry snowboarding, or high-speed skateboarding. Soccer is also popular in the United States now, although football is still more popular. One of the riskiest new sports is skysurfing, in which people jump out of airplanes with boards attached to their feet. Skysurfing rivals skydiving and bungee jumping for the amount of thrills and risk.
