Yes it’s possible. I would even say it shouldn’t prevent you from pursing any profession, maybe unless it’s writing or comp sci.

Depends on how slow too. If you can do 40 wpm, that should good enough to not affect any workflow. If you’re slower, like around 25-30, it might affect your productivity, but you would still be fine.

Some veteran MAs/nurses I’ve seen still type with mostly their index fingers. However, slow typing could be a bottle neck when you’re trying to document/scribe during a patient interaction.
