Have you ever noticed how your computer gets slower over time? Those of you with Macs are probably less likely to know what I am talking about. But you Windows users who frequently surf the web understand.
The internet and our computers have become complex ecosystems of viruses and programs interacting in ways that we cannot predict. Your computer accumulates viruses or other malware by virtue of simply doing day to day activities. Over time these accumulated bits of interacting code (malware and programs) start to slow down your computer. Like an aging mind. What if the aging process is a result of a biological equivalent of the over accumulation of “programs” and “malware”?
Over the course of our evolution, our DNA and our Microbiomes may have accumulated opportunistic life-like processes (some life forms too) that cause us to age. I don’t want to limit it to life forms as we know it because there are some biological processes and interactions that are somewhat life-like, but not exactly alive.
Unlike a computer, our operating system is not so easily hacked. Hence, it takes generations for other life processes to cozy up to a larger organism like us and integrate. The end result is the same. A gradual overload/decline of/in the system. Maybe we can develop some sort of a biological “Norton Antivirus” that goes in and removes the harmful life processes that cause us to age.
