For people who has difficulty concentrating, I can highly recommend The Isolator! The helmet will help you focus on what you're doing by closing out all sound while pumping you full of oxygen, at the same time it limits your vision to a tiny slit.

This is also a fantastic thing to own! A full face swimming mask from the 1920s, that was designed to protect women's faces from the sun. Not scary at all...
