下面一段短文中，有两处系以中文呈现，请利用上下文线索（如单字、词组等）将其译成正确、通顺、达意且前后连贯的英文。

　　We are sometimes forced to take expensive tests to determine if we are healthy. However, our bodies often tell us all we need to know. Paying attention to the handwriting on the wall can teach us what is and isn't normal.

　　Changes in the color, odor, and texture of the stuff that comes out of our bodies can signal danger. 

1. 虽然讨论这些东西可能有点难为情，但它们很容易就能分辨出来。

For example, healthy mucus in the nose and throat is clear or white. Yellow or green mucus is a sign of bacterial infection. Changes in our bodily functions can also provide clues about our general health. For example, there are over 500 causes of diarrhea, and it can be serious if it happens for days on end. 

2. 据说指甲上的白点也是一种缺乏钙质（calcium）的征兆。

The truth is that those white spots could just mean you use your hands a lot. By learning to read our bodies' natural signs, we can decide whether we just need a few days of rest, a lifestyle change, or a trip to the doctor's office.

1. 第一句可译为：

Although these things might be embarrassing to talk about, they are easily recognizable.

2. 第二句可译为：

It has been said that white spots on one's fingernails are also a sign of calcium deficiency.

 

参考中译

　　我们有时会被迫接受要价昂贵的检查来判定我们是否健康。然而，我们的身体经常透露出我们想要知道的一切。注意这些不好的征兆能让我们知道身体哪里正常以及哪里不正常。

　　身体所排放的物质在颜色、味道与质地方面的改变可能代表了危险的警讯。虽然讨论这些东西可能有点难为情，但它们很容易就能分辨出来。举例来说，健康的鼻涕是透明或白色的。黄色或绿色的黏液便是细菌感染的征状。身体机能的改变也能提供整体健康状况的线索。举例来说，有五百多种因素会导致腹泻，而且如果情况持续好几天，那可能就很严重了。据说指甲上的白点也是一种缺乏钙质的征兆。但事实上，白点可能只是意味你用手过度。藉着解读这些我们身体上的自然迹象，我们就能决定自己需要的是休息几天、还是要改变生活方式，或是去找医生看看。
