I used to ask my late father (who worked for a newspaper) and/or my late wife (who was also a journalist) to have a look at my work before I submitted it.
The Faculty of Occupational Medicine requires candidates for Membership to submit at dissertation. I supervised a trainee, whose dissertation won the Faculty's prize medal that year.
I attended the AGM to bathe in my trainee's reflected glory, and I cornered the Chairman of the dissertations committee afterwards, and asked why my trainee had been awarded the prize. "Well", he said "From a scientific point of view, there was little to choose between the two dozen or so dissertations which were submitted, but where your trainee's effort really stood out was because it was a pleasure to read!"
My wife, who was not a scientist, deployed her skills as a journalist with the proof-reading, as well as translating three German and two French language papers.
