I picked up a book and started to casually browse through the pages. I had to go down stairs (three floors). I started walking while still reading the book and I noticed that I could "see" everything around me while still concentrating on the book. I made it all the way to the basement like this, down two flights of stairs.
Is this an example that Photo reading is having an effect on me? Also would it be a good idea to practice this (without climbing up and down the stairs for safety sake).
