Encounter with Barry Black

I think it was four years ago, the last time i met Dr. Barry Black. He was preaching during chapel at Pioneer Memorial Church in Berrien Springs, Michigan (Andrews University). I didn't get to talk to him personally. But I read his autobiographical book and knew somewhat about him. He has been blessed with photographic memory and thus able to recite the whole bible, both old and new testaments, from memory. I thought that people with these kinds of abilities are disabled in some other way. However I could find no flaw in him. He interacted with people normally, talked, sang, walked normally. And as far as i know had no problem doing any other ordinary tasks. And so I found some articles and websites regarding people with photographic memories. Sure enough some things I didn't know before was that the original term for it is Eidetic memory. People with eidetic memory don't have to be autistic. But I was associating autism with it because the only people that are widely known to have this ability are autistic savants. I also found out that this phenomenon is still scientifically non explainable. I sure wish i had this ability as well. But only very few are fortunate of having this ability.
