Internet is killing your brain
People who smoke usually know that smoking might prematurely kill them. Or if not kill, then give them cancer, stroke, heart disease, lung disease and etc. People who drink alcohol are aware that they will have liver problems and might prematurely die. Eating processed food leads to obesity which in turns might lead to cardiovascular disease. Its all known, its hard to argue with it, the data is there (look at sources in NHS, WHO, CDC). But very few people know that internet damages your brain.
