从我们的第一声啼哭到最后一次呼吸，我们的身体正经历着不断的微妙变化。我们的每一个本能动作以及从外界受到的每一次刺激，都通过我们的皮肤、骨骼、器官、肌肉以及细胞得以体现。我们一生中平均呼吸7亿次，成年人的骨架每7-10年更换一次，身体每分钟会死掉3万个皮肤细胞，我们吃下的食物从口至肛门要经历9米的旅程。这些看似稀松平常的细微瞬间，其实都是我们赖以生存的生物系统奇妙的变化过程。
现在，国家地理频道（NGC）将采用显微摄影技术、先进的医学技术和心脏断层（CT）显像技术，带领你一起进入人体的肌肤深处，与你一同见证我们从幼年、青年、成年到老年过程中，人体是如何运作、成长和成熟的。

Christopher, fifteen years old, stands beside Mrs Shears’ dead dog. It has been speared with a garden fork, it is seven minutes after midnight and Christopher is under suspicion. He records each fact in the book he is writing to solve the mystery of who murdered Wellington.

He has an extraordinary brain, exceptional at maths while ill-equipped to interpret everyday life. He has never ventured alone beyond the end of his road, he detests being touched and he distrusts strangers. But his detective work, forbidden by his father, takes him on a frightening journey that upturns his world.
