This is personal… I mean… A personal endeavor… task… something for myself. An act of discipline? Certainly, an attempt at organization of my thoughts and notes. It’s also giving a purpose to all the time consumed in writing and calculations, for which, doubtlessly, there has been a price to pay… It’s motivation: to continue to put those millions of neurons in the brain to good use as the signs and symptoms of age start showing up and letting their marks…  This blog, in essence, is an exercise in economics, a way to redeem myself. The visitor, if any, shall not look beyond that. Just enjoy what you can.
