I don't want to ring any alarm bells, but...
Last year, I was running a beginner's course, there was a young girl (About 15ys) who developed a pain in her wrist in week 3. Her mother took her to the Doctors for a check up. (I gave the young lady all the information she needed to take to the Doctor, ie, arrow length, bow poundage etc.etc.) The following week, they came back to me to say that after the Doctors examination, she would not be completing the course. It seems that her wrist would never be strong enough to take the strain, & that as a coach, I did the right thing in giving the info' to take. I'm pleased to say that I was in no way responsible for the wrist injury. This was from the Dr.
I thought it a very nice thing for them to come back to tell me, instead of just sending a letter or 'phoning.
This could be a warning to all coaches running courses: Keep your records up to date. I do a questionnaire for all would-be archers coming to my courses. When the course has ended, I give the paper to the archer concerned for them to keep or dispose of, as they see fit. I do not keep those records on electronic files.
I hope Greenmans' junior is able to keep up the archery.
