Imagine that your life began roughly 300,000 years ago?as one of the planet’s first humans.?At this time, you live in Africa near modern-day Morocco,?and your life isn’t too different from that of your hominid parents.?You make crude tools, hunt, and gather food and materials,?until, eventually, you perish.?But this is only the beginning.?Because after dying, you travel back in time to be reincarnated?as the second human ever to live.?While you don't remember your former life,?your previous actions affect you nonetheless.?And after dying once more, you return as the third person, then the fourth,?the fifth, and so on—?living the lives of every single human that’s ever walked the Earth.

想象一下，你的人生 從大約 30 萬(wàn)年前開(kāi)始了，?而你是地球上最早的人類之一。?此時(shí)此刻，你住在非洲， 接近如今的摩洛哥，?你的生活和你的原始人父母 并沒(méi)有什么太大的區(qū)別。?你會(huì)做粗糙的工具，打獵， 收集食物和材料，?直到迎來(lái)死亡的那天。?但這只是個(gè)開(kāi)始。?因?yàn)槟闼篮?，又穿越回去?轉(zhuǎn)世成為了史上第二個(gè)人類。?雖然你不記得你前世的事，?但是你之前的行為還是會(huì) 影響你的這一世。?死了一次又一次以后， 你轉(zhuǎn)世成為了第三個(gè)人、第四個(gè)人，?第五個(gè)人等等……?你會(huì)經(jīng)歷地球上 每一個(gè)存活過(guò)的人的人生。

Strung end to end, these lives last almost 4 trillion years.?Since you only recall the life you’re currently living,?your psyche doesn’t carry the entire weight of human history.?However, each of your lifetimes still has a profound impact on your future selves.?Sometimes your influence on the world is obvious,?but these major historical figures only account?for a tiny fraction of your experience.?Instead, your existence consists mostly of ordinary lives,?filled with everyday tasks like eating, laughing, working, and worrying.?For approximately one tenth of your 4 trillion years,?you’re a hunter-gatherer.?For 60%, you’re an agriculturalist, developing tools and techniques?which you employ over roughly 800 billion years of working on farms.?Across your lifetimes, you spend 1.5 billion years having sex?and another 250 million years giving birth.?In total, 20% of your existence is spent raising children,?to whom you impart a variety of cultural values?that influence the trajectory of generations.?In some lives, you shatter those cultures through invasion and imperialism.?In others, you suffer as your lands and loved ones are taken away.?In over 1% of lives, you’re afflicted with malaria or smallpox,?while, in others, you treat these conditions—?saving countless versions of yourself.

這些人生頭尾相連 要持續(xù) 4 萬(wàn)億年。?由于你只能記住 你現(xiàn)在所處的這一世，?你的腦子不會(huì) 肩負(fù)整個(gè)人類歷史的重?fù)?dān)。?但是，你的每一次人生 都會(huì)對(duì)未來(lái)的自己產(chǎn)生深遠(yuǎn)的影響。?有時(shí)，你對(duì)世界的影響很明顯，?但是這些重大的歷史事件?只是你經(jīng)歷中的滄海一粟。?相反，你的存在 大多由平淡日常組成，?充滿了日常行為，如吃飯、 歡笑、工作、焦慮。?你的 4 萬(wàn)億年中 大約有十分之一的時(shí)間?作為一名狩獵采集者。?有 60% 的時(shí)間，你作為 一名農(nóng)學(xué)家開(kāi)發(fā)工具和技巧，?用于長(zhǎng)達(dá)約 8000 億年的務(wù)農(nóng)。?縱覽你的人生， 你在性生活上花了 15 億年，?又在生孩子上花了 2.5 億年。?總共有 20% 的時(shí)間 花在了養(yǎng)孩子上，?你得把會(huì)影響世世代代延續(xù)的?各種文化價(jià)值傳給你的孩子。?在某幾段人生中，這些文化 會(huì)因?yàn)榍致院蛿U(kuò)張分崩離析。?在某幾段人生中， 你會(huì)因家破人亡而備受折磨。?有超過(guò) 1% 的時(shí)間， 你在經(jīng)受瘧疾或天花的折磨，?但是在其余的時(shí)間里， 你能治療這些疾病，?拯救了你的好幾世。

In humanity’s early days, the average lifespan is fairly short.?There are fewer lives to live,?and your influence is usually limited to people physically near you.?But as humans survive longer on average and Earth's population grows,?you start to spend more time reliving the same action-packed years.?A full third of your existence comes after 1200 CE,?and a quarter of it takes place after 1750.?At this point, technology and society start changing faster than ever.?You invent steam engines, configure factories, and generate electricity,?which power the daily machinery of all of your later lives.?You live through revolutions in science, the deadliest wars in history,?and dramatic environmental destruction.?On average, each new life lasts longer,?but the pace of your existence keeps accelerating.?Conversations that previously took months to unfold now happen in minutes.?Business ventures that you built over generations transform overnight.?You enjoy luxuries you never could have sampled before,?even in your past lives as kings and queens.

在人類早期，平均壽命挺短的。?你只能活一小段時(shí)間，?于是你的影響力通常僅限于 真正在你“身邊”的人。?但隨著人類普遍越活越久， 地球上的人口越來(lái)越多，?你開(kāi)始重復(fù)經(jīng)歷 那幾年豐富多彩的人生。?你有整整三分之一的時(shí)間 是在公元 1200 年之后，?有四分之一的時(shí)間 是在 1750 年之后。?此時(shí)此刻，科技和社會(huì) 以前所未有的速度快速發(fā)展。?你發(fā)明了蒸汽機(jī)， 開(kāi)了工廠，生產(chǎn)出了電力，?為你余生所用的 常見(jiàn)機(jī)械提供了動(dòng)力。?你經(jīng)歷了科學(xué)革命、 史上最致命的戰(zhàn)爭(zhēng)?和劇烈的環(huán)境破壞。?基本上每一段人生都更長(zhǎng)了，?但是你經(jīng)歷的節(jié)奏越來(lái)越快。?以前要花幾個(gè)月進(jìn)行的對(duì)話 現(xiàn)在只要幾分鐘。?你花了幾世建立起的企業(yè) 一夜間就轉(zhuǎn)型了。?你享受著之前 從未體驗(yàn)過(guò)的奢侈品，?就算是國(guó)王王后的 那幾世也沒(méi)有機(jī)會(huì)體驗(yàn)。

After living over 100 billion lives,?you're finally reborn as the youngest person alive today.?But despite living through 300,000 years of human history,?your actions have more impact today than 99% of your past lives.?High-speed air travel allows you to carry contagions and cures?across an ocean in hours.?And the internet makes your personal sphere of influence global,?allowing you to collaborate with anyone, anywhere, without even leaving your home.?In recent lives, you’ve invented tools to rewrite the genes of living organisms,?permanently altering their future generations.?And in this life, you might create even more technologies?that make the world safer, kinder, and more equitable for countless future lives.?However, one careless invention could just as easily be catastrophic.?Between nuclear weapons, lab leaks, climate change,?and other existential threats,?humanity's risk of inducing our own extinction has never been higher.?In this fast-paced, interconnected world,?it’s frighteningly easy to undo all of humanity’s progress,?or potentially, cut short all your possible futures.

活了超過(guò) 1000 億世以后，?你終于轉(zhuǎn)世成為了 當(dāng)下最年輕的人。?雖然你活過(guò)了 人類歷史的三十萬(wàn)年，?但是你的所作所為在此刻產(chǎn)生的影響 比過(guò)往 99% 的人生都大。?高速航空旅行可以讓你在幾小時(shí)內(nèi)?傳播疾病、傳遞藥物。?互聯(lián)網(wǎng)把你的個(gè)人影響力 擴(kuò)散到全球，?讓你可以與任何人在任何地點(diǎn)合作， 甚至不需要離開(kāi)你家。?在最近的幾輪人生中， 你發(fā)明了工具改寫生物的基因，?永久改變了這些生物的后代。?在現(xiàn)在的這段人生中， 你可能會(huì)發(fā)明更多的科技，?讓世界對(duì)于無(wú)數(shù)的未來(lái)生命 更安全、更友好、更公平。?但是，一個(gè)無(wú)意間的發(fā)明 都有可能會(huì)引發(fā)災(zāi)難。?核武器、實(shí)驗(yàn)室泄漏、氣候變化?和其他關(guān)乎人類存續(xù)的威脅，?人類把自己推向滅亡的風(fēng)險(xiǎn) 到了史無(wú)前例的高度。?在這快速、互聯(lián)的世界中，?要想抹消人類所有的進(jìn)步，?或者切斷你所有未來(lái)的可能 簡(jiǎn)直易如反掌。

There's no way to know what will happen next.?But what’s clear is that your potential is limitless.?So, how will you spend this life??And what can you do to work towards a better future?for all your lives to come?

我們無(wú)法知曉接下來(lái)會(huì)發(fā)生什么。?但顯而易見(jiàn)的是 你的潛力是無(wú)窮的。?那你會(huì)如何度過(guò)此生呢？?為了給你接下來(lái)的每一次輪回 爭(zhēng)取一個(gè)美好未來(lái)，?你能做些什么呢？
