Typing is becoming tiring

I haven't written on here due to weakening hand muscles and the fact that typing for any length of time really knocks the starch out of me. I'm still dong okay....walking (although clumsily), eating (but altered consistency), breathing seems to have stayed about the same since diagnosis (FVC March 2013 was 70%, December 2013 it was 68%) I keep busy watching movies and older TV shows. I'm on the 5th season of Mash, first season of Mannix, second season of China Beach, etc. My wife is a great care giver...she helps me shower, dress, take meds, custom prepares 90% of my meals and anything else that I need assistance with.
