Paragraph 1
We can count the
of rings on a tree to find its age. Scientists have now found we can measure the
of people by getting them to stand on one
. Dr Kenton Kaufman said standing on one leg shows how
a person can balance, and
becomes more difficult as we age. He said balance was
because, "it requires input from
, the [hearing] system, and the [senses]". He added: "Good balance provides the
to carry out activities of daily
without the fear of falling, and this leads to improved quality of life and
ageing."
