While in High School I took physics. The professor was certainly what I would call a "Science Geek". Thick horn rimmed glasses with faded yellow lenses, a pocket protector, slicked back hair and an inability to communicate his passion for physics to a room full of pubescent students. In addition my teacher had tunnel vision, his visual field was limited, so he could only see what was directly in front of him. This made for interesting classroom dynamics because anyone outside of his field of vision had an advantage when it came to the passing of notes, cheating and talking in class. Needless to say this affliction was not an asset to his teaching.

The words "Tunnel Vision" came up in my home recently. My husband commented that I had "tunnel vision" in terms of all things blood type related. I was not particularly offended by what he said, but it did cause me to think about why he would say that.

Possibly it is because every one I meet I try and guess their blood type, from TV characters to my neighbors and coworkers. I will repeatedly say to my husband, "I think he is an O... or maybe a B". I know if he ate differently he would be able to run that marathon and actually build muscle tissue." (my husbands eyes roll lovingly and he smiles)

I recently saw some old friends that I hadn't seen for quite some time, I quickly rattled off all their blood types, they stood amazed that I remembered this detail about them. It is not that I want to remember, it seems I simply can't keep the information out of my head. If someone tells me a health complaint, in my mind I am trying to decide which GenoType they are, "must be a Gatherer if the thyroid is bothering him."
Or maybe he said I have tunnel vision because I study the lists of foods or maybe because I reread the books over and over, for tiny tidbits of information.
Or because I will wake him in the middle of the night with some dream that centered around the people I love having there lives changed by eating for their type.

I am not sure why he would accuse me of having tunnel vision but I don't mind at all.
