The fist bump: A more hygienic alternative to the handshake
碰拳头：比握手更卫生的方式
The handshake is a commonplace greeting in many cultures, but it has the
potential to transmit infectious organisms directly between individuals. We
developed an experimental model to assay transfer of bacteria during greeting
exchange, and show that transfer is dramatically reduced when engaging in
alternative so-called dap greetings known as the high five and fist bump
compared with a traditional handshake. Adoption of the fist bump as a
greeting could substantially reduce the transmission of infectious disease
between individuals.

今天看到某英文杂志的一篇文章说到
互碰拳头可能降低传播疾病的风险，比起握手大幅减少了传递的细菌
有没有英国人做这篇研究的八卦?
