This undated photo provided by NOAA in May 2018 shows aurora australis near the South Pole Atmospheric Research Observatory in Antarctica. When a hole in the ozone formed over Antarctica, countries around the world in 1987 agreed to phase out several types of ozone-depleting chemicals called chlorofluorocarbons (CFCs). Production was banned, emissions fell and the hole shriveled. But according to a study released on Wednesday, May 16, 2018, scientists say since 2013, there’s more of a banned CFC going into the atmosphere. (Photo by Patrick Cullis/NOAA via AP Photo)

“Cosplay, short for “costume play”, is a type of performance art in which participants don costumes and accessories to represent a specific character or idea. Cosplayers often interact to create a subculture centred around role play. A broader use of the term "cosplay" applies to any costumed role play in venues apart from the stage, regardless of the cultural context”. – Wikipedia. (Photo by Luffy Monkey D.)

There are many types of hobbies. Some of them are strange, such as piercing your skin with huge metal hooks with ropes attached to them, and dangling yourself from the ceiling. Others might enjoy riding down huge mountain hills on skis, snowboards, mountain boards, bikes, etc. However, some enjoy pastimes that are more tranquil and meditative. For example, the art of contortionism is a very peculiar hobby that is usually practiced by women and children, due to the natural stretchiness of their tendons. Despite the fact that tendons of grown men are usually too stiff, a Berlin-based dancer is able to do amazing things with his body and is not afraid to show it to the world.
