The average human lifespan has increased significantly over the last 100 years (34.1 years to 72 years, respectively), yet for the same period of time the maximum human lifespan is basically unchanged at 115 years. Is this truly the maximum lifespan for human beings? (There are some outliers who have lived a small number of years longer.)
Here is a research paper from the NIH/NIMH that disagrees with the assertion that 115 years is the maximum lifespan for humans:
Well I’m concerned about the obesity types of things… I think they are getting worser and worser by the year and I don’t know how that’s going to change
And antibiotic resistance
My own spiritual beliefs say there was a different maximum but I won’t push those here. It’s still interesting though. I’m curious to know why one person lives to fifty and another who is a centennial. I wonder how old my generation will live to but bad diet, stressful jobs, sedentary lifestyles, and poor choices make it difficult to ascertain.
I once read an article that it’s going both ways. In areas that won’t be able to afford medical advancements you won’t see much change, but if you can afford it, they estimate age a child born today could live into their 130s
I read that given telomere lengths, the maximum lifespan is about 120 years. If telomeres can be lengthened artificially, then people might be able to live longer.
In some sense, each of our cells has a biological clock. It is doomed to die after about 60 reproductions.
The Hayflick limit is the number of times a normal human cell population will divide until cell division stops. Empirical evidence shows that the telomeres associated with each cell’s DNA will get slightly shorter with each new cell division until they shorten to a critical length, turn into senescence and eventually die.
This whole process roughly takes about 120 years. Sounds like a familiar number?
Before we set our minds to increase lifespan, we should ask ourselves a critical question: do we deserve to live that long? On this already overcrowded planet, what qualifies us for eating up resources crucial to our great grandchildren?
My high school physics teacher once said that she saw things like air crashes, wars, and natural disasters that result in death as population control. I loved her up until that moment.
