    Like Indiana Jones (a fictional character), who undertakes daring adventures in his spare time, my father is a businessman by day and a thrill-seeker by night.

His enthusiasm rubbed off on me, and I have been lucky to be his companion on many adventures. We started out by riding America’s fastest, most twisted roller coasters. After that a whitewater rafting trip through the Grand Canyon（峡谷）on the Colorado River started our search for other extreme thrills across the globe.

Amazing thrills awaited us at every corner of the world. Skydiving was especially thrilling when performed from a helicopter over the breathtaking Swiss Alps. We have bungee jumped from the world’s highest platform, Bloukrans Bridge in South Africa. Most recently, in Interlaken, Switzerland, we attempted canyoning（溪降运动）.

Anyone who loves a challenging thrill should try canyoning. Our adventure began with a 90-foot rope down a canyon wall into a rushing ice-cold river. Then we crossed the bone-chilling water toward the mouth of the river, our final destination, where the reward for the journey would be a whole view of the beautiful Interlaken basin. We slid over slippery rocks at one moment, jumped from waterfalls and swam through underwater tunnels the next. Back and forth we alternated, climbing rope ladders before going back into the fresh mountain water. Certainly, danger was waiting for us in each of these activities, but that very danger provided the rush. Canyoning was indeed one thrill after another, from beginning to end.

While canyoning is possible only in certain places, thrills and adventure can be found anywhere. Our beginnings in the U.S. showed us just that. We continue to seek the big thrills, but in doing so, we have learned to seek lesser excitement in daily life as well. After all, we can’t go canyoning every day, and small thrills are better than none for us thrill-seekers.
