A skin cell does many vital jobs over the course of it’s life. It is arguably part of the more defensive oriented aspects of our biological economy. Each cell lives and dies, in part, to protect the whole body that gave birth to it and nourished it to maturity. Skin cells share a common legacy with all cells, to serve nourishing and, or defensive roles in relation to the community, whose integrity depends on enough of that shared value for the interdependent community to survive, and if there is a sufficient commitment to that end, to flourish.
The whole process takes around 6 weeks, from being “born”, to being pushed up through the layers in about 4 weeks, to dying and serving even in death for about two weeks as part of the stratum corneum. (Outer layer of skin) Other cells in our body live much longer, but all that are significant (not antagonistic to the body) are also aligned around the purpose of nourishing and defending the whole community which also nourishes and defends them.
My guess is this statement made through this biological economy, happens on many scales. It applies to biological organisms like us in reference to the ecological economy in which we live and on which we depend as a species. Finding and serving this role of constructive service is also the difference between a significant life and a meaningless life for us. It seems to depend on whether or not we found and played a role, no matter how small, in leaving something more constructive in our wake than the sacrifices that had to be made for us to be here at all.
This understanding and constructive expression of significance strikes me as the key to a satisfied life. We appear to be biologically wired to be satisfied by finding and expressing our nourishing and/or defensive role in the context of the community. I am pretty sure this is why we never meet anyone who is both malignantly selfish to the parasitic and predatory exclusion of others, and satisfied at the same time. Again, as far as I can tell, this move toward constructive significance seems to make the difference between an existence that is both to the self and frustrated in terms of purpose, and one that is more reflective of recognizing and fulfilling a role that supports the relationship economy on which we all depend for our present and our future. It is also the way evolution makes selective decisions about what will continue forward in time, and what will be selected out.
