Hej!
I hate to be the lone voice of dissent, but it would personally drive me crazy. I have ADHD, and one of its characteristics is the inability to automatically ignore distractions.The erratic , percussive nature of the sound a typewriter makes would be absolutely impossible to ignore- I know this from personal
experience: when I was a child, my mother used to type late into the night, in the room right next to my bedroom, amd then wonder why I didn't fall asleep, or couldn't focus on schoolwork.
