繁體中文譯本

Your heart pumps 2,113 gallons (about 8,000 liters) of blood every day, and the blood vessels it travels through could stretch around the world 2.5 times over. Your eyes can recognize 70 million different colors and, in your lifetime, will produce 143 pints (67.7 liters) of tears. The human body is a source of a wealth of incredible figures – figures that are laid bare in Discovery’s Body In Numbers.

你的心脏每天会输送2,113加仑（约8,000公升）的血液，而血液行进的血管延展开来足以环绕地球2.5圈。你的眼睛可以辨识7千万种不同的颜色，而在一生当中，你会制造143品脱（约67.7公升）的泪液。人体蕴藏着一大串不可思议的数据，而这些数据将在探索频道的《人体密码》中一一揭晓。

In episode one, we’re taken on a journey from conception through to our first birthday. It all starts with a single cell measuring only two thousandths of an inch (0.005 cm) across. The cells quickly grow in number, and adult bodies usually contain around 100 trillion of them. But let’s get back to that first one. It’s formed at the moment of conception, when all the information from our father is added to that of our mother, and our very own DNA, or biological blueprint, is created.

在第一集当中，我们被带入一段从受孕到1岁生日的旅程。一切都始于一个直径只有千分之二英吋（0.005公分）长的单细胞。细胞数量迅速成长，而一个成年人体内通常有约100兆个细胞。不过让我们回到最初受孕那一刻形成的细胞，此时父亲和母亲身上的信息加在一起，因而产生我们自己独特的DNA（生物蓝图）。

After that, our cells begin to multiply and form the different parts of our body. This process happens quickly. After just over three weeks, our heart starts beating, another five weeks on and all our organs have developed. We’re even able to detect the world outside the womb less than halfway through a pregnancy. And the changes don’t stop when we’re born. Fueled by large quantities of milk, our brain develops and our body more than doubles in weight during our first 12 months of life. But this is just the start of the journey; there’s a lot more to discover when we examine our body in numbers.

在那之后，我们的细胞开始以倍速成长并形成身体的不同部位。这个过程发生地非常迅速。仅过了3周，我们的心脏就开始跳动，而再过5周，我们所有的器官就已发展完成。我们甚至可以在孕期还不到一半时就侦察到子宫之外的奶水的营养与能量，在我们生命刚开始的12个月当中，大脑不断发展，而体重也增加了两倍以上。但这只是旅程的开端。当我们以数字来观察身体时，还有更多可以探索。

The human body is a wonderful machine, unparalleled by anything found in the man-made world. To keep it running smoothly requires a diverse combination of ingredients, the most important of which is simple H₂O. Water makes up about 70% of our total weight, and we’d collapse after just a couple of days without it. Our bodies also contain large amounts of carbon and calcium, enough to fill 9,000 pencils and make 266 sticks of chalk. Our bodies also contain tiny amounts of titanium, gold, and even uranium.

人体是一部令人惊奇的机器，人造世界当中没有任何事物能出其右。要让身体顺利地运作需要各种不同成分的组合，其中最重要的就是简单的水。水构成我们总体重大约百分之七十，只要几天没有它我们便会倒下。我们的身体也含有大量的碳与钙，足以充满9,000只铅笔以及制作266根粉笔。我们的身体更包含少量的钛和金，甚至是铀。

These elements aren’t the only things that keep us going, though. We also need sleep, about 26.5 years of it over the course of an average lifetime. These hours give our brains time to sort through what happened in the day, organize memories, and discard the thousands of things that aren’t worth remembering. It’s also the time when the body fights off infections and repairs cuts and bruises.

然而这些元素并不是让我们支撑下去的唯一事物。我们也需要睡眠，在人类的平均寿命期间，睡眠约占了26.5年。睡眠的这几个小时让我们的头脑能够整理一天所发生的事、组织记忆，并且摒弃不值得记住的数千件小事。这也是身体击退病菌感染以修补伤口与瘀血的时间。

The human body’s ability to mend scrapes or heal broken bones is remarkable, but over time, the body doesn’t so much repair itself as completely rebuild. We could replace all the skin on our bodies in just three weeks. Over a lifetime, that would be enough to cover 1,352 people. And it’s not just skin; we replace our entire blood stream every four months, and before we die, we’ll produce bone to make 12.5 skeletons – that’s one big Halloween party!

人体愈合擦伤和修复断骨的能力很了不起，但随着时间的推移，与其说身体自我修复还不如说它能完全重建。我们可以在短短3周内替换身体的所有肌肤。在一生当中，这多到足以覆盖1,352个人的身体。不只是肌肤，我们每4个月便会汰换所有的血液，而在我们死之前会长出足以制造12.5组骷髅的骨头──那可是一场极盛大的万圣节派对呢！

It’s incredible what you learn when you start looking at the body in numbers, so make sure you watch this fascinating Discovery Channel show – you’ll never look at yourself the same again.

当你开始以数字看身体时，能学到的东西令人难以置信。所以务必要锁定探索频道这个引人入胜的节目──你将不会再以同样的方式看自己。
