Funny story man I have a mild stutter and like everyone else man we stutter all the time. But once I what to Spain( a place I been wanting to go for 4 years) I volunteered at a hostel though Worldpackers and was a tour guide, I cooked and cleaned and when I I was there for 3 months my stutter pretty much disappeared. I not sure what it was, could have been the amount of social interaction I got every day or the fact that I was in a new place I never been before but I know I need to go back to Spain. Once I got back to the us within 2 weeks my stutter came back pretty much to what it was before I left.
