The Unmentioned Trade-Offs in Life Extention
Now it is not that the cell biologists can’t point to experiments which seem to fit their views, as is common in natural science. (After all, the Earth’s Moon does indeed have a geocentric orbit.) Good colleagues of mine like Robert Reis are able to produce nematode worms that live ten times longer than their unmutated controls, if they use ingenious genetic and environmental manipulation. But nematodes have well-developed physiological machinery for sustaining states of metabolic arrest,...From Michael R. Rose's "Immortalist Fictions and Strategies"

Cognitive Neoteny in Modern Humans
The boy-genius can be seen as a specific instance of psychological neoteny which is apparently adaptive in modernizing cultures, and it occurred early in science because science is one of the most ‘modern’ and advanced social systems [2]. ‘Neoteny’ refers to the biological phenomenon whereby development is delayed such that juvenile characteristics are retained into maturity. It represents a relatively fast and simple way of evolving adaptations – for instance modern humans in Weste...Perpetual education and change has pushed humans into a perpetual state of youthful cognition. Our brains remain childlike in order to continue to learn and adapt to our ever-changing modern environment.
