That’s living for ya.
They call it a ‘terminal decline phase’. Excuuuse me?
Your ability to compare figures will go before your spatial ability which in turn will go before your verbal ability. But it is all down, down, down until your whole body crashes.
The start of the decline is different for various cognitive abilities.
- Perceptual speed, which measures how quickly people can compare figures, begins declining nearly 15 years before death.
- Spatial ability starts declining nearly eight years before death.
- And verbal ability starts declining about six-and-a-half years before death.
