An overview of a study on the shape of our learning. I suppose it is no mistake that tertiary education systems follow the curve. "A seven-year study (published in the journal Neurobiology of Aging) reveals the average age at which the top performance was achieved as 22 in nine out of the 12 tests given. The first age at which there was any marked decline was at 27 in tests of brain speed, reasoning and visual puzzle-solving ability. Things like memory stayed intact until the age of 37, on average, while abilities based on accumulated knowledge, such as performance on tests of vocabulary or general information, increased until the age of 60."
