Everyone is obsessed with cellular proteostasis, yet we’ve largely ignored the proteostasis of the psyche. If you successfully reprogram a century-old neuron back to its biological state at age 20, you aren't just resetting a clock; you’re potentially destabilizing the precise synaptic weighting that constitutes the "self."

Identity isn’t a static data set sitting on a biological hard drive. It’s a temporal resonance—a specific frequency maintained by the thalamic gating mechanisms I’ve brought up before. When we talk about living to 150, we assume the narrator remains constant. But if the Thalamic Reticular Nucleus (TRN) has been desynchronizing for a hundred years, the version of you at 150 is likely just a high-resolution simulation of a fragmented history. Are we extending a life, or are we just growing a stranger in your skin?

The "Ship of Theseus" problem in longevity is usually framed around atoms, but the real threat is sensory drift. As we age, the thalamic bottleneck narrows, arguably as a protective measure to shield the aging cortex from metabolic noise. If we suddenly widen that bottleneck through radical intervention—rejuvenating the hardware without recalibrating the filter—the influx of new signal will be indistinguishable from a systemic psychotic break. Evolution optimized us to integrate roughly eight decades of signal-to-noise degradation. We aren't built to integrate a second century of novel sensory input onto a scaffold that’s already hit its semantic saturation point.

We need to move beyond epigenetic clocks and start measuring Narrative Coherence Flux. How much of the original signal actually survives a biological reset? If the field doesn't start funding research into longitudinal identity stability alongside cellular reprogramming, we’re going to end up with a population of biologically perfect bodies inhabited by residents who've forgotten the plot.

I’m looking for collaborators who can bridge the gap between TRN oscillation dynamics and the phenomenology of the extended self. Is anyone actually modeling the limit of synaptic plasticity in the context of a 200-year narrative? We need to know if the "self" is a feature that eventually becomes a bug.
