The ultimate life force lies in tiny cellular factories of energy (근본적인 생명력은 에너지의 미세한 세포공장에 안에 놓여 있다), called mitochondira (미토콘디라라 불리는), that burn nearly all the oxygen we breathe in (이것은 우리가 들어 마시는 모든 거의 모든 산소를 태운다). / But breathing has a price (그러나 호흡은 대가를 치른다). / The combustion of oxygen that keeps us alive and active sends out by-products called oxygen free radicals (우리를 살아 있고 움직이게 하는 산소연소는 활성산소라는 부산물을 내 보낸다). They have Dr. Jekyll and Mr. Hyde characteristics (그들은 저킬과 하이드 박사의 특성을 갖는). On the one hand (한편으론), they help guarantee our survival (그들은 우리의 생존을 보장하는 도움을 준다). For example (예를 들어), when the body mobilizes to fight off infectious agents (신체가 감염된 병원균과 싸우고자 준비할 때), it generates a burst of free radicals to destroy the invaders very efficiently (그것은 침입자를 아주 효율적으로 파괴하기 위해 활성산소를 폭발시킨다). On the other hand (다른 한편으로), free radicals move uncontrollably through the body (활성산소은 신체 전역에서 통제할 수 없게 이동한다), attacking cells, turning their fats rancid, rusting their proteins, piercing their membranes and corrupting their genetic code (세포를 공격하고, 세포지방을 신패하게 바꾸고, 세포의 단백질을 부식 시키고, 세포의 막을 뚫고 세포의 유전자 코드를 오염 시킨다) until the cells become dysfunctional and sometimes give up and die (그 세포가 고장을 일으키게 되고 때때로 포기하여 죽을 때까지). These fierce radicals, built into life as both protectos and avengers (보호자이자 보복자로서 생명체의 이 사나운 활성산소는) are the potent agents of aging (노화의 강력한 작용제이다).
