Mountain climbers are very brave people. In the mountains they risk their lives every minute. There are no roads or paths in the mountains but there are a lot of high rocks and streams which are hard to cross.Climbers often take dangerous routes nobody used before them.They start getting ready for the climb long before it begins.Firstly they choose the mountain and look it up in all kinds of books,they make brief notes and study the information.The more they know about the mountain they are going to climb the better.Then , if they go climbing in another country,they've got to think about their passports.The most important thing is to prepare the equipment including food and medicines.It's easy to get injured in the mountains.Though there is a rescue service in many countries,mountain climbers must be prepared for all kinds of accidents.
