" As soon as they no longer hurt I forgot about them. A 'normal' condition to my brain didn't call for attention."

Yep...thats how it works, thank goodness. If we normally 'remembered' and dwelled on all the sad & uncomfortable & frustrating things that have happened, it would be quite a mental turmoil.

I just recently repaired a toilet downstairs that had leaked and not refilled properly for several years...(obsolete parts were found on the WWW)...and now I'm 'almost' used to just flushing it without having to monitor the process and open & close the valve at the wall. It is really nice occasionally glance at some former problem and realize it IS now 'normal'.
