Will Biotechnology Stop Aging?

Could biotechnology stop aging? The answer may be yes, no, or something in between, depending on who is being asked and what it means to “stop” aging. For those at one end of the spectrum— life extension seekers (including some deep-pocketed Silicon Valley investors)—the answer is “yes.” They believe biotechnology will lengthen human life spans to range anywhere from 1,000 years to forever. But for most, the answer is more nuanced and involves a dream of extended healthspan, rather than immortality.

We know that there are variants of diabetes now—outside the typical Type I and Type II diabetes—that respond very, very [differently to treatments], and their complication rates are very different than what’s been traditionally thought of in diabetes that have the genetic variants of that.” Genomics, in many cases, provides the ability to see a condition through a new lens.

Baby, Where Did You Get Those Eyes?
