When José Ángel Salazar was 14 years old, he became the youngest conductor in the world. Born in Nueva Esparta, Venezuela, José Ángel didn't listen to much classical music during his childhood. When he was eight years old, his father and grandfather took him to a brass band concert, and his life changed forever. He stopped going to karate lessons and learned to play the flute. Soon afterward, he decided to learn the violin. n 2011 José Ángel auditioned to join the Symphony Orchestra of Nueva Esparta, where he continued studying violin and music theory. The following year, he was asked to become the orchestra's conductor. Although conductors usually have their backs to the audience, they are the most important person in an orchestra. Apart from indicating the beat of the music, the conductor interprets how the music is played. He uses different movements, gestures, and expressions to communicate with every individual musician. There are between 70 and 80 musicians in the Youth Orchestra of Nueva Esparta, and more than half of them are older than José Ángel. "It's hard because I have to find the way to communicate, or sometimes tell off kids who are much older than me," he said in an interview with the Guardian newspaper. "Conducting is a wordless language. I have to convey confidence to the musicians in order to get a confident performance back I have to coordinate my body's movements with the music." from them... José Ángel is also aware of the importance of words for a conductor. "I'd like to study languages. I don't want to go on tour and have to use a translator. Or if I'm interpreting Mahler, there are certain criteria, or feelings, that I'd have a better grasp of if I spoke German."

Man's best friend Sydney - A mongrel has proven that dogs are really man's best friend, when he helped rescuers find the body of his owner who was killed in a car crash in Australia. Moja, a small mixed breed, was in the truck with his owner Henry Drew when it crashed off a highway in Queensland and landed in dense shrubs. The animal sat by Drew's body, which was hidden by trees, barking incessantly for two days until a farmer went to investigate the cause of the noise. "If it were not for the man's dog, he may not have been found for some time because his truck was completely covered by trees and our helicopter couldn't see it." a rescuer said. Drew had been reported missing by his wife after he did not answer his mobile phone. Rescue helicopters worked with police to search for him until the farmer called.

I have at the professional level for many years now, and I've even won a few tournaments su Target archery is a very popular sport, and it is particularly popular in my country. You could almost call it a national pastime for Koreans. There are even archery cafés in Korea! This might be why South Korea is known for producing some of the most talented archers in recent years. In fact, South Korean archers grabbed gold medals in all four categories of archery at the 2016 Rio Olympic Games. The rules of target archery are simple. Archers shoot at a stationary target. Indoor competitions take place at 18m. Outdoor ranges can be from 25m to 90m. Each match is divided by ends which are counted as either three or six arrows. Archers shoot their arrows at a target with ten rings drawn on it. Each ring's value gets higher as it nears the center. After firing all shots, archers add up their scores and the archer with the most points at the end of the competition wins. GEOCACHING Hello, I'm Andrew and I have been an active geocacher for more than ten years. Geocaching is an activity for people who love exploration and adventure. It's essentially a giant game that involves using Global Positioning System (GPS) receivers to search for hidden treasures called geocaches. There are all kinds of geocaches. Some are very simple to find and others require the participant to solve puzzles to learn the cache's location. What waits inside each cache is a mystery. Geocaches can contain all sorts of different treasures, such as CDs, books, USBS, and even money. One common item in almost every geocache is a logbook. The logbook is a record of all the participants who have found the cache and contributed to it. 1 If you're interested in seeing what treasures lie out there, you can try this activity out yourself. Look online for nearby geocaches. There may be some nearby. Find one and then set off on your first geocaching adventure. All you need is a smartphone and a little bit of time to join in the fun.
