As revealed in Season 1, in a conversation between Sean and the Techman, a company named Chronos, way back in 2045, figured out how to secure the telomeres on the right genes and turn off the biological clock. When a host of nasty side effects, including death, resulted from the Chronos formula, the company went under and a company called Genfinity took up the reins and perfected the process. Now, in 2159, most people, once they reach their early to mid 20s, shut off the aging process. Together with the eradication of life-threatening disease, natural death became a thing of the past. Even most injuries that were considered fatal a century ago are no longer so. Most body parts can be replaced and even brains and consciousness can be transferred to new bodies. In 2159 there are a few million people walking around that look like they are in their 20s but are closer to 140 in chronological years.
Only the most catastrophic injuries by accident, suicide, violent crime or act of war are the remaining causes of death. As discussed in previous blogs, there are some who choose to age naturally. They are known as agers. With enhancements, organ replacements and the lack of disease, the life expectancy of an ager is nearly 150 years.
The matter of what to do with an unlimited lifespan is another question. As reported in an earlier blog, the suicide rate in New Asia is extremely high. Apparently, after a hundred years some people actually get bored with it all or become weary of pleasure and find life meaningless. The oldest living human in 2159 is a man who switched off at age 81 back in 2047. That makes him 193 in chronological years. The jury is still out on how multi-centenarians will feel about their lives in the next couple of centuries.
