I run into people all the time with mild to moderate sensory problems. Because I have learned to manage most of my sensory problems (mine are mostly severe), I help random strangers regularly figure out how to deal with their sensory issues.

I don't know if the reason I run into so many people with sensory issues is that I run in multiple "nerdy circles". Most of the nerds I know and have met are sensory avoiders. Studying just gave a lot of them the excuse to stay away from large groups of people on a regular basis.

I have run into adult sensory seekers, although not as often. One was so hyposensitive that he never noticed when he broke bones or displaced his shoulder right away. It was really only until the injuries healed poorly and the number of injuries piled up that he realized that he had a problem.
