For example, a vague warning against diabetes is a lot easier to ignore than the fact that your risk of diabetes is 22% (as mine is, slightly above normal), but that you can lower it substantially (as I have) by eating right, exercising, and so forth.
比如说，人们经常会忽略一些关于糖尿病的笼统警告，但当你发现自己的糖尿病风险是22%时（跟我一样，稍高于正常值），就会留下深刻印象并像我那样通过控制饮食，运动等行为来降低这个比率。
