  • around 7 octillion to be exact.

  • These make up the 37 trillion cells in your body, which are actually much younger than you think.

    這些組成了我們身體裡 37 兆的細胞,他們比你想的都還年輕許多

  • The cells that lie in your stomach regenerate every 5 days,

    像是在胃裡面的細胞平均每五天就再生一次

  • Your skin's outer layer, known as the epidermis, is shed every two to four weeks,

  • In fact, studies have shown that after viewing 2,500 images for only 3 seconds,

    受試者還是能夠以 92% 的準確度指出他看過了哪些影像

  • Don't believe your eyes? Maybe it's because you spend 10% of the day blinking

    你不相信你的眼睛嗎?可能是因為你一天之中有 10% 的時間都在眨眼

  • meanwhile your fingers can feel a ridge as small as 13 nanometers in size.

    還有你的手指也能感覺到 13 奈米的觸感

  • That's 7500 times smaller than the diameter of a human hair.

    13 奈米相當是一跟人類頭髮直徑的 1/7500

  • And while you may not think much of your pinky finger, without it, you'd lose 50% of your hands strength.

    你可能覺得你的小拇指沒什麼用,但沒有他,你手掌的力量就會少掉 50%

  • Sure, the index and middle finger are essential to help pinch and grab with the thumb,

  • but it's your ring and pinky finger that give your hand power.

    但無名指跟小拇指卻是提供你的手力量

  • Now clasp one hand into the other - that's roughly the size of your heart!

    心臟每天跳十萬下,每個脈搏輸送 5.5 公升,一年大約輸送三百萬公升的血

  • If you live to 75, it would fill 90 Olympic size swimming pools.

    如果你活到 75 歲,心臟的輸血量能灌滿 90 個奧林匹克游泳池

  • When it's all setting down, human decomposition begins around 4 minutes after death.

    當心臟停止運作,四分鐘之後身體就會開始腐敗

  • This process is known as self-digestion, in which your enzymes and bacteria eat you away.

    這過程就是所謂的自體溶解,身體裡面的酵素與細菌會開始啃食

  • In fact, three to five pounds of your body is made up of bacteria.

  • In an unclean mouth alone, 100 million to 1 billion bacteria can grow on each tooth,

  • And from the bones of our ancestors, we can extract DNA to learn about them.

    我們還可以從過去人類的骨頭中,萃取出 DNA 得到類似結論

  • But if we were to take all of your DNA from your entire body and uncoil it,
