I am listening to an audiobook of Bryan Stevenson reading Just Mercy
and I recently finished Alex Pollock Finance and Philosophy. Pollock calls it "ironic" that people might want, or even plan for and achieve, a "long and recreation-filled retirement." He believes our expectations about retirement are 60 years outdated, and we really need to work into our mid- to late-seventies. He makes no mention of Simple Living, but I consider SL to be a fair means to financial independence, be that attained at 50, 55, 65, or whatever.
I enjoyed Pollock's Compendium of Aphorisms, which includes this nugget from Jacob Viner: A period of transition is a period between two periods of transition.
