If all goes well, Brin won't age, either, or not past a certain point. Slowing or stopping that process is the current focus of biochemist Ned David, co-founder of Unity Biotechnology, who is 49 but, according to Friend, looks 30. The scientist's youthfulness is part of his appeal, writes Friend.

　　如果一切进展顺利，布林将不会变老，或者，不会突破某个年龄界线。 生化学家奈德•大卫目前将其研究的重点放在延缓或停止衰老进程，身为统一生物技术机构的联合创始人，他虽然已经49岁了，但在弗兰德眼中，他看起来只有30岁而已。弗兰德写道，奈德的这种青春状态，也是他需求的一部分。

　　Investing in bio-tech breakthroughs is one way the super rich are trying to stay young and healthy indefinitely. Others in the community are settling for cryogenic freezing, in the hopes that they can be thawed once regenerative science has sufficiently advanced.

　　超级富豪们试图永葆青春和享受无尽的健康的途径之一便是在生物技术方面投资。“长寿圈”里其他人则倾向于于将他们的器官冷冻起来，等到再生技术充分发展之时再将其解冻。

　　CNBC reported in 2016 that "thousands of people around the world have put their trust, lives and fortunes into the promise of cryonics." At that point, at Alcor's center in Scottsdale, Ariz., nearly 150 individuals had elected to preserve either their heads ($80,000) or their entire bodies ($200,000) in liquid nitrogen.

　　2016年，全美广播公司财经频道曾经报道“来自全世界的成千上万的人们都将他们的信任，他们的生命及财产交与了低温冷冻技术”。就在那时，安国公司位于亚利桑那州斯科茨代尔的中心选出了150人，将他们的头(80,000美元/人)或身体(200,000美元/人)用液氮冷冻。

　　If there is a way to "solve death," as Friend puts it, whether through cryonics or gene therapies, a kind of vampirism in which Silicon Valley billionaires "end up being sustained by young blood" or more wholesome methods such as good nutrition and medicine, some combination of the above or perhaps an actual sorcerer's stone, the next generation of well-funded alchemists is determined to find it.

　　正如弗兰德所说，若“阻止死亡”的方法真的存在，不论是通过低温冷冻还是基因疗法(即“吸血鬼症”，得了此病的富翁们最终只能靠吸收新鲜血液来维持生命)，亦或是采用更加全面的手段，如摄入营养品或药物，资金充足的术士一定可以找到让人长生不老的诀窍，它可能是以上几种手段的组合，也可能是一块真正的魔法石。

　　As a 30-year-old start-up founder confidently tells Friend, "The proposition that we can live forever is obvious. It doesn't violate the laws of physics, so we will achieve it."

　　一位30岁的企业创始人满怀信心地对弗兰德说：“我们想要长生不老的意愿显而易见，它并不违反物理学定律，因此是可以实现的。”
