It might sound crazy to the masses, but life extension is a real thing. The science, also known as anti-aging medicine, indefinite life extension, experimental gerontology, and biomedical gerontology, is the study of slowing down or reversing the processes that create aging. The result? Maximum and average lifespan extended. The question is, do we need tech? Or should we begin to look at why our life spans aren’t already longer?

If you try to envision it, you might find yourself lost in a futuristic sci-fi film you’ve already seen. But it’s more than a concept fit for the silver screen. Life extension is a very real science, and is currently being worked on as you read this.

According to some scientists, we are mere decades away from moving into life extension, which could change life as we know it forever.
