Me: All from belly buttons?

我：这些全来自于肚脐眼？

Our belly buttons - or really, the bacteria they contain - are reflections of our lives.

我们肚脐眼——或者确切讲，里面的微生物——是我们生活的写照。

Jiri Hulcr, who leads the project, says they collected samples from hundreds of belly buttons.

吉瑞﹒虎克担任这个项目的负责人，他说为了这工作，收集了上百号人肚脐眼里面的东西！

In the pool, meanwhile, whites have the advantage because they have longer torsos, making their belly buttons lower in the general scheme of body architecture.

与此同时，由于白人的躯干更长，跟普通人的身体结构比起来，他们的肚脐更低，因而在泳池中，白人更有优势。

When Hulcr resampled some belly buttons after a couple months and dozens of showers, their bacteria — the same bacteria from before — were still growing happily.

当虎克两个月后又再次从试验者肚脐眼收集样本时发现，虽然是让他们当中一部分人洗了个澡才收集的，可他们的微生物朋友——和之前的一模一样——依旧长势喜人。
