nothing or anything
I have always doubts when I have to use the words " nothing" and "anything"; So could you tell me , please, if the following sentences are correct :
-When I was a child , I lived with my parents in a small farm; they bred pigs, and each year, in automn they used to kill one of them . Pork was considered as a staple at that time. When people killed a pig, each part of the animal was used like the blood, the brain or even feet; farmers did not throw away anything .
