So I was rewatching some of DS9 season 7, and all the Worf/Ezri/Jadzia drama got me thinking. So you're an unjoined Trill, let's say around age 20. You get a symbiont. You live with it for 50 years, you die, and it gets a new host. Does the new host have have just 50 years worth of memories from you, or the entire 70 that that humanoid trill lived for? Essentially, does the symbiont pick up stuff that you experienced before becoming joined?
