We get it. You're saying the same thing over and over. You do presumably realize that, being 70, they have no way of pushing a button and suddenly being 35 to pass your apparently magical test of significance to their actions. Given that as smart as they are they can't invent an age reducing time machine but they did encounter what they consider to be serious issues at the institution where they worked in their 70's and did not encounter similar serious issues where they worked in their 30's, what exactly would you have them do that passes your personal threshold of significance test for their actions?
