there are very few numbers that I remember , I'll tell you a brief story, I got food poisoning a few years back and was really weak one day after , wife took me to Walmart , I left my cell phone in the car.. I came out and couldn't find her car anywhere, went back in the store to call her and couldn't remember her cell phone number, was overwhelmed with anxiety. ended up walking the entire parking lot until I found her. I never get out of the car without my cell phone now.
