Let's see:

  do {
    4 h HN;
    4 h family;
    4 h coding;
    4 h sleep;
    4 h emails;
    4 h meetings;
    4 h teaching/supervisions;
    4 h grant/paper writing;
    4 h reading;
  }
  while (breathing);
  //
  // ----------
  // 36 h / day
  // ==========

But only some of the meetings and grant writing feels like real "work"; the rest feels more like "I'm getting paid for my hobby" (including for reading HN, no kidding), and if it wasn't my job I would be paying money to be allowed to do it.
