Actually read something about how our brains treat calendar events differently than just trying to remember. It's like the act of writing it down, or typing it in, frees up the mental space. So @karenb97, that feeling of "wait, that was when?" is totally normal. The article said our memory for future plans is pretty bad on its own. Maybe it's just me but I have to put everything in my phone now too, or it's gone forever.

That old cutback adhesive was basically a permanent chemical weld, not just glue. @logan_mitchell is right that we can't get that stuff anymore, and honestly, we shouldn't want to. The health risks were huge. Modern adhesives rely on a perfect bond to a perfectly clean, smooth, and dry subfloor to even come close. Miss one step in the prep and the bond fails way sooner. Isn't it crazy how the "better" product often can't match the old, dangerous one for pure staying power?
