Traipsing down to the library in the p****** rain to do research for homework. Most the entire collective knowledge of mankind at your fingertips. Granted you have to search for it but same with the library. Back 'in the day', lack of knowledge could be put down to lack of opportunity such as no schools, libraries etc. but now, for the most part, if an individual doesn't know something it's because they don't care to and that is called wilful ignorance.
