Undid the annoying tendency to update dates that represent a milestone, thus losing that milestone of note. If it happened then, then it's a continuation of that status since then. Until it becomes untrue, *then* a new edit can be made.

-Irwin died in 1991. Shepard and Conrad died in 1998 and 1999 respectively, making the total 9 as of the date this comic was published. Since then, Armstrong died in 2012, Mitchell in 2016, Cernan in 2017, Young on January 6, 2018, and Bean on May 26, 2018. The death of Bean kept the actual line almost in line with the 50% 'actuarial line', though it had generally been at least slightly higher prior to that. The situation by January 2025 saw the factual line stay at 4, taking it again beyond the 95% for at least the time being.<!-- Not wishing to tempt fate, just updating... Also deliberately removing the awkward "as of" phrase, 20/Jan/2025--> The oldest living person to have landed on the Moon is Aldrin at 95<!--b. January 20, 1930-->. Also living are Scott at 93<!--June 6, 1932-->, Schmitt at 90<!--July 3, 1935-->, and Duke at 90<!--October 3, 1935-->.

 The chart assumes that no other humans will go to walk on another world within the time-frame plotted and the title text implies that this is primarily an economically determined decision. While noting that not exploring space is a justifiable and sensible decision which may also be made by many hypothetical cultures on other worlds, the text implies a grandness to a civilization that would be given the opportunity to discover, study and memorialize the 'one-world graves' of other civilizations by choosing to explore space despite the economic difficulty. This also implies that the likely consequence of not exploring space is that a civilization which chooses to do this is doomed to go extinct eventually while those which do explore and colonize may last long enough to be safely established on multiple worlds and discover the remains of civilizations which acted on a purely economic basis and hence ensured their own collapse. High five for exoplanet archaeology.
