There was a time when I used to be amazed at the guy who I would see every day walking to work and reading a book. I have no idea how he managed to concentrate and know where he was going. I knew I would be more than likely to trip over something and be a bloody mess. I just thought it was really good how he would have his head in a book. Now it is head in a smartphone, texting and walking at the same time. I am still amazed they can do both at the same time but how times change.
