I have a stuttering problem and I've had it my whole life, sometimes it is severe but most of the time it is mild to moderate. Ever since I have increased how much time I play destiny a day it has gotten worse and I just noticed it. My speech therapist told me she has done a study on this and it is true she has facts behind it, that video games do increase stuttering in a person that has a stuttering problem. So I decided not to play for 2 days and my speech has improved by a pretty notable amount. This sucks cause I love destiny but my speech is more important to me.
