Researchers claim they have debunked a long-standing misconception of the mathematical model of human mortality that predicts a set limit on aging. Their discovery comes as good news in a time of increasing breakthroughs in anti-aging therapy.

The mortality rate in animals and humans alike is governed by the Gompertz mortality law, a model that predicts the probability of death based on two fundamental components: the age-independent Initial Mortality Rate (IMR) and the age-dependent Mortality Rate Doubling Time (MRDT). The two were believed to be universally related by the Strehler-Mildvan (SM) inverse correlation, a theory popularized in 1960 after its publication in Science. It basically indicates that after a certain age (around 30 in humans), the probability of death increases exponentially with time and that any interim anti-aging interventions are mostly futile.

In a recent publication in the Journal of Theoretical Biology, a research team of the biotech company Gero addressed the uncertainties of the Gompertz model. Digging through data of excessive cohort survival studies on C. elegans, they successfully pointed out a fundamental discrepancy in the Strehler-Mildvan correlation within the Gompertz model, finding it´s merely a degenerate consequence of improper fitting rather than biological fact.

“We worked through the entire life histories of thousands of C. elegans that were genetically identical, and the results showed that this [Strehler-Mildvan] correlation was indeed a pure fitting artifact,” group leader Peter Fedichev said.

Fedichev and his team were not the first to question the soundness of the Strehler-Mildvan correlation assumption, but they were the first to really show it arises as an artificial property and not a biological coincidence. Their discovery comes with impeccable timing, as accumulating evidence shifts more and more scientists to address aging as a disease.  On top of that, exciting anti-aging therapies are being developed faster than ever. Yet another home run for humanity!

    Have you ever wondered what it would be like to have an android body? What about mind uploading? I do not believe that mind uploading will offer immortality or life extension because it will not actually be you. While it is a way to live on, you would just be able to see a new version of yourself from your old body. Even as an android, I imagine you may have difficulties. For instance, food and alcohol would not be the same. I have written a fictional story about a person who has uploaded his mind into a perfect android body. You would think he would be living in a dream. But he will find that his past will come back to haunt him. My story is called A New Self by Roy Wells. You can borrow the book for free if you have a Kindle and Amazon Prime. I hope you enjoy it!
