Educational sites and free courses from world-renowned universities and top lecturers are useful for all age groups. Currently (due to geographical or financial circumstances) many people are not able to travel to further locations to acquire knowledge and improve existing knowledge. A simple solution is online teaching led by top world lecturers and universities.
