Помогите, пожалуйста, перевести текст.

 

When rapping started in New York, new dances were invented. First, there was break dancing. This often involved spinning your body around on the floor but it is no longer popular. Later, the electric boogie appeared. With this, the dancers moved like robots, twitching their bodies in time to the music. Nowadays, there is free style - dancers just do what they want! If you look at the fashions of the 'Hip Hop' culture, you can see the choice of clothes was influenced by the way of dancing. You needed loose clothes to do break dancing. Also, you need comfortable shoes and trainers seemed the best style. The fashion for trousers hanging below the hips has a different origin. Unfortunately, a lot of young people from the Bronx have had prison experience. Prisoners have to remove their belts so they can't use them as weapons. As a result, prisoners would walk around with their jeans hanging low. When these young men were released, they brought this habit to their neighbourhood. And this style became popular with many young men who didn't realize where it came from.
