I find it amazing that someone could capture all those images in their head. It just makes me feel that we all think differently like the 60 Minutes Show where Mary Lou Henner from Taxi and some other individuals could recall long ago dates and times of events and explain it perfectly as if it happened just moments earlier; this man has the good fortune to be able to snare the information and retain it long enough to draw a tremendous picture of all those acres and acres of the city. I wish we could all unlock our brains like that and draw the picture we have in our heads or anything else for that matter.
Scientists have said we only use 1/4 or our brain power at any given time in our life. Apparently, the unused 75% is able to be accessed but almost none of us know how to do it. Stephen, however, can and does access that very mysterious portion. Unbelievable!
