Reading, something I've always done and enjoyed since a young child.
I remember we moved to Wales when I was around 6 years old, first day at a 'new' school the class had to take turns reading aloud from a book, I was told nicely to slow down because the others couldn't follow in their books quick enough.
Just lately had a couple of occasions where I start a book (ebooks) and find after a couple of chapters that I've already read it years ago, I guess it's an age thing
