I am almost completely unable to write anymore. I've been typing for 2/3rds of my life and haven't done any serious pen writing for the last 15 years. I'm sure with some practice I could get used to it but I don't see a need. Keyboards are just more natural to me. I learned to write English and spell via QWERTY. In fact I don't really know how many words I type are spelled. I just know what sequence of key-presses are required to make them. My understanding of grammar is tied to the ability to quickly edit. It's trial & error grammar. Sometimes I have to type something out a few times to determine what is proper grammar or at least passable as a coherent sentence. I've noticed when I do write with a pen my spelling & grammar skills revert to the level they were at when I stopped writing 15 years ago. (significantly worse)
