Reader question: Jonathan Moeller vs. carpal tunnel!

Reader Twell asks:

“Good lord, man! How on earth do you do it? There’s only a few romance writers that put out more books, and I’m betting that those are actually teams of writers using a single pen name. At the least, you must be using voice recognition, otherwise you’d be crippled by carpal tunnel years ago.”

I don’t use voice recognition. I type everything (and I write everything myself – no co-writers). How do I avoid carpal tunnel (also known as repetitive stress injury, or RSI)?

Short, glib answer: pushups! Lots and lots of pushups.
