There is a difference between going back to work and being fully recovered. With your sternum cracked open you can be back to work, I was in under three months, but not fully recovered for a long time afterwards. A service writer probably doesn't have to pick anything heavy up in the course of his work. I had to carefully plan any heavy work and called in for help more than once, which I don't have to do now. I guarantee after 4 months Stumpy won't be bench pressing an A833 into place. Heck I don't anymore and it's been over three years.
