Wow, @Lilmo, that is quite a story. I hope that you're making steady progress in your recovery.

Have you checked out any free online games to boost working memory? Many are designed for kids (my own kids play them to help "remember their place" as they shift from task to task in a multi-step project), but I'm sure there are resources for adults as well.

You bring up such a great point - I think we could all stand to gain from improving brain function!
