  1. What interesting information! i wonder if that process may sometimes lead to little accidents where some neurological conditions may arise – such as learning difficulties, ADHD, autisim spectrum disorder, or propensity for bad mental health, after nature’s overzealous ‘shedding’ (for want of a better word) of neurons – & if genetics might play a part in the process.
