Who is Bull-Hansen?Bjorn Andreas Bull-Hansen (born 1972) is a Norwegian novelist, blogger and YouTuber. Born in Oslo, Bull-Hansen decided to become a writer when an automobile accident on December 22, 1995 left him injured and unable to continue education towards an economics master's degree. He had previously won several prizes in powerlifting, including two gold medals in the Norwegian Powerlifting Championship, a bronze medal in the European Championship, and fifth place in the world, as well as several Norwegian records. The stories in Bull-Hansen's novels tend to be set in hostile environments, and he has written both from Iron Age settings and from a post-apocalyptic world. His characters are often troubled and it is easy to see that Bull-Hansen's experience working with people shines through in his novels. He was a therapist before becoming a full-time writer.
What is Coronavirus?Coronaviruses are a group of viruses that cause diseases in mammals and birds. In humans, coronaviruses cause respiratory tract infections that are typically mild, such as the common cold, though rarer forms such as SARS, MERS, and COVID-19 can be lethal. Symptoms vary in other species: in chickens, they cause an upper respiratory tract disease, while in cows and pigs they cause diarrhea. There are yet to be vaccines or antiviral drugs to prevent or treat human coronavirus infections.
What is Face Mask?A face mask or respirator is a device designed to protect the wearer from inhaling hazardous atmospheres. These include fumes, vapours, gases and particulate matter such as dusts and airborne microorganisms. There are two main categories: the air-purifying respirator, in which respirable air is obtained by filtering a contaminated atmosphere, and the air-supplied respirator, in which an alternate supply of breathable air is delivered. Within each category, different techniques are employed to reduce or eliminate noxious airborne contaminants. Air-purifying respirators range from relatively inexpensive single-use, disposable face masks sometimes referred to as a dust mask to more robust reusable models with replaceable cartridges often called a gas mask.
