Huernia zebrina, or Lifesaver plant, is one of the best in this category. Lifesaver cactus plants are easy to grow in small dish gardens or even bonsai containers. The biggest challenges with Huernia cactus care are overwatering, incorrect lighting and mealybugs.
What is the average speed on a ski? For regular downhill skiing the average is about 15-20 mph Olympic ski racing averages 40-50 mph and The fastest recorded speed is 156 mph here is my source http://www.trails.â¦com/facts_9654_how-fast-do-downhill-skiers.html.
Downhill skiing is  the speed event of the alpine skiing. Downhill courses have long straightaways, difficult turns, steep passes and hills that send the skier flying over bumps through the air. The extreme speed of the downhill course (up to 90 mph on some courses) puts the racers at great risk of injury.
