I would consider non-tradtional to be someone very unlikely to attend law-school given their circumstances.Since the deaf student doesn't have any life circumstances that would make attending law school unlikely, I wouldn't characterize him as non-traditional.
don't you have anything better to do then browse messageboards?
I think if you get down to choosing between two students with equal GPA/LSAT, Similar Undergrad schools, etc. An older student with quality experince will have a slight edge. For, example, military service seems to be valuable. I don't mean Natioal Guard. If you served 10 years as an officer, pilot, etc. Maybe spent some time in a war zone. That seems to help.If you spent a considerable amount of time helping others that makes for a good personal statement. Just being older does not help. Sometimes it can hurt. Older students have had more chances to screw something up. That doesn't make iy "fair", just reality.
