Invited to china in 1977 to talk about his great discovery , a virus that caused hepatitis , and his greater invention , a vaccine to prevent it , he would slip out in the early mornings to run for hours through fields , farmyards or the just-stirring streets of beijing .

他曾于1977受邀前往中国就新发现乙肝病毒，以及他伟大的发明乙肝疫苗，进行演讲，他会老早起床溜出去穿过旷野、院落，或者就在北京人来人往的大街上跑上几个小时。
