Still sharp. In fact, really do feel my brain is engaged at the moment, getting a lot done and sorted. One tiny little thing that has helped with this is whiteboard.com. It is a collaborative space where several people can edit the same webpage easily. I just use it as a place to write a list, that I can access from any computer. Makes life lovely and simple, and replaces the endless pieces of paper that end up in my pocket. It is nice and straightforwards to set up and use too.
