It's all down hill from here

According to research, my mental powers began to dwindle a couple of years ago.
Professor Timothy Salthouse of Virginia University found reasoning, speed of thought and spatial visualisation all decline in our late 20s.

Therapies designed to stall or reverse the ageing process may need to start much earlier, he said.

His seven-year study of 2,000 healthy people aged 18-60 is published in the journal Neurobiology of Aging.....

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.
