Paragraph 1
Scientists in Germany have cast
on a previously believed assumption that the
speed of our brain starts to decline from the age of 20. Until now, it has been thought that our
level peaks when we are 20 and declines thereafter. Lead researcher
Mischa von Krause, of Heidelberg University, offered hope to
people who worry about increasing forgetfulness or reduced brain
. He said cognitive
were still powerful at the age of 60 and do not diminish before then. He wrote: "Our
is encouraging, as our results show that average levels in mental speed in
demanding fast and forced decisions do not decline until relatively late in the
."
