Scientists say they have found key clues（线索）into how long we will live. One of them is a firm     21    . British researchers believe a firm strong handshake is not just a     22     of confidence but also an indicator of a long life. Lead author Dr Rachel Cooper of University College London said her study looked     23     33 different reports on the     24     of handshakes. The research involved more than 50,000 men and women and     25     40 years. Dr Cooper concluded that     26     with weaker handshakes were 70 per cent more likely to die earlier than those with the     27     handshakes. She concludes that people with a firm strong handshake     28     from a happy childhood that     29     a healthy diet and     30     of exercise.
The new study,     31     in the British Medical Journal, also found other signs of living a longer life. These 'measures of     32     capability' include walking at a faster pace, getting out of a chair quickly, and being able to     33     on one leg. The study showed that slow walkers were almost three times     34     to die at a younger age than those who walked quickly and actively. Those who     35     to get up from their armchairs were twice as likely to die earlier than those who sprang     36     their chairs. Dr Cooper believes there     37     more research into the link      38     physical capability and a long life. “Research that helps people to     39     a long and healthy life is ever more important to help provide for an ageing     40    .” she said.
