Extreme sports are not for everyone. But for people who enjoy 1) (live) life to the full, they are the only type of sports worth 2) (do)! The latest extreme sport to become popular is sandboarding. It involves 3) (slide) down extremely high sand dunes on a board. You can 4) (lie down) or stand up. When standing up? Both your feet are tied to the board to prevent you from 5) (fall off). Some sandboarders, however, prefer 6) (keep) their feet untied because it allows more freedom of movement. Lying down can be even more fun. Can you imagine 7) (speed) headfirst down a sand dune at 80 km/hr? Because that’s how fast you can expect 8) (go)! Sounds like fun? People who have tried sandboarding say it’s totally addictive! So head to a desert and try it out. You don’t need 9) (have) any experience, but you should 10) (love) danger and excitement!
