Are you browsing NSFL stuff all day or something? I used to spend inhumane amounts of hours looking at this type of shit while normally eating food. At least in some points there is some educational stuff like medical gore and you get to see the effects of some disease, viral/bacterial/microbial infections, effects of heroin and other drugs that sometimes lead to necrosis, some interesting analysis on corpses that gives you some insights in anatomy... it is not just shock value, there is a lot of educational stuff in it too.
This type of stuff helps a ton whoever wants to work in forensics or in the medical field, either to learn anatomy, injuries/traumas, reconstruction, desensitising to the visuals you will have to see and thigs like that.
