hello, I am new and wasnt exactly sure if this belonged here or not. I heard that there is a point in your chin where if you hit it it will cause your nerve to shake or somthing and you will lose mobility in your legs for a short time. I wasnt sure if he was messing with me or if he was being truthful. If there is such a nerver in your chin or any other pert of your body where would it be located?
