Where did the person get such statistics from? Nigeria may not be progressing but Nigerians are very good at adapting to any situation. being angry or displeased with something doesn't equal depression. Despite the happenings in nigeria, nigerians are among the most happy people in the world because we know how to find our way in shitty situation. So i don't agree with the statement that "90% of nigerians are plunged into depression "
