A mind is a terrible thing to waste - or to tinker with haphazardly. I'm reminded of when Palm came out with "Graffiti", their stylus-stroke way of entering western characters into the thing. Folks were hospitalized with aphasia, where they couldn't figure out how to write normally any more. They'd jumped the well-work grooves they'd been in since primary school and couldn't find their way back.
As adults we are a wired mess of stimulus-response formed by uncoordinated childhood and young-adult experiences. To start pulling those wires and plugging them in elsewhere, risks losing something. Maybe something you value.
