In certain ways, McCain was a natural Web candidate. Chairman of the Senate Telecommunications Subcommittee and regarded as the U.S. Senates savviest technologist, McCain is an inveterate devotee of email. His nightly ritual is to read his email together with his wife, Cindy. The injuries he incurred as a Vietnam POW make it painful for McCain to type. Instead, he dictates responses that his wife types on a laptop. Shes a whiz on the keyboard, and Im so laborious, McCain admits.

One form of torture is breaking the bones in the fingers, or the knuckles of the hands. That would make it very painful to type or even write.
