It can be used for anything. And can be used in any topic or situation. Like Cold in America or Common Cold in America is a different thing but seeing these situations it's too cold in USA at this very moment.

In 2023 it's a record that USA is going through a huge coldest temperature. A human body can resist at 5°C as it's the lowest optimum temperature that the enzymes of a human body can tolerate. After it getting lower temperature the enzymes are getting deactivated i.e the minimum operating temperature of an enzyme is required to make reaction . 

So in this situation people of America are having many problems like freezing etc. The outside of their house and the road is covered with ice . The pets and other Street animals are also having such problems. It's an horrible climate. 

So in this case as a future doctor I would like to give suggestions that people should rub their hands to warm up and consume rum for warm up body. Also fire the bones at chimney to be warm and keep the pet warm.

Experts are saying that it may lead the climate change in near future as the same thing is observed in past. So as to save the climate we must save the nature first.

It's also a responsible of people that to keep Street animals as many as they can . So that they also survive from this cold. This will show the kindness of humanity towards the animals. Thank you
