Paragraph 1
Scientists have cast
on a common
that the brain's processing speed declines from the age of 20. Until now, scientists believed our
level peaks at 20 and declines thereafter. Lead researcher doctor Mischa von Krause gave
to older people who worry about
or reducing brain power. He said cognitive
were still powerful at the
of 60. He wrote: "Our
is encouraging, as our results show that
levels in mental speed in contexts demanding fast and forced decisions do not decline until
late in the lifespan."
