That used to be me too, up late, in the sack virtually never before midnight, one, two. That 20 years ago up all night couple of times a week. Then the mini-stroke, anti-clot tablets, shortness of breath and - lol - a time flip. Now get roughly seven hours (interrupted) somewhere roughly between eight and three, nine and four. Roughly. Sometimes five-six hours from 10. Know exactly how you felt last night (yours, 3:34 pm here now) so tired yet kept posting away. LOL Sleeping soundly now, i hope.
It was Plato who said, “He, O men, is the wisest, who like Socrates, knows that his wisdom is in truth worth nothing”
