I would select any of the immediate visual types of disabilities. As we all know, stammering is a hidden disability. It rears its ugly head when we start to talk. I personally hate with a strong and emotional passion being a person who stammers. My thinking and as Ill rational as it is, that having a more prevalent disability, like down syndrome, or being in a wheelchair, along those lines would make it easier to have interactions with the public. Stuttering has absolutely destroyed my life.
