Firm Handshakes

British researchers say a firm handshake could be a sign of a longer life expectancy. Scientists found that elderly people who could still give a firm handshake and walk at a brisk pace were likely to outlive their slower peers. They found simple measures of physical capability like shaking hands, walking, getting up from a chair and balancing on one leg were related to life span, even after accounting for age, sex and body size.
