i would like to know more about mountain climbing
Great topic! While mountain climbing or mountaineering began as attempts to reach highest points, it's now branched into specializations of rock-craft, snow-craft, and skiing. 
cool what else
In order to stay safe, you have to be physically fit but also have good technical knowledge about climbing and mountains.
that seems very tough
One of the toughest climbs is Mount Everest. It is 8844 meters high and is located between China and Nepal.
wow that is very tall anyone ever climbed it
Yes! Many people have climbed it. In 2017, there was 600-660 summiters!
