4. RUBBING SOAP ON THE WHOLE BODY
4.全身涂肥皂

Soap dislodges dirt and oil from the body, allowing water to wash it away.
肥皂去除身上的污垢和油脂，水就會把它沖走。

But the skin on the arms and legs doesn't contain a lot of oil, so cleaning them with soap just makes them dry.
但是胳膊和腿上的皮膚并沒有很多油脂，所以用肥皂清潔只會使它們變干燥。

Instead, people should concentrate on soaping the odorous parts of the body - the armpits, buttocks, groin and feet, said Dr Mahto.
反之，人們應該集中涂肥皂于身體有異味的部位——腋窩、臀部、腹股溝和腳，馬赫托博士說。

As the skin gets thinner and drier as we age, older people should use less soap to prevent flaky skin, she added.
隨著年齡增長，皮膚會變得越來越薄、越來越干，老人應該少用肥皂，防止皮膚變薄，她補充道。
