Would like some advice on cover letter--moving away from bedside nursing

I am also looking to transition away from the bedside. I am going to say that I want to transition away from the bedside and utilize my clinical skills in another manner. I am planning on saying the physical demands of the job are too much and I can't do the lifting anymore. I also want to utilize my nursing and computer backgrounds and do something in informatics.

I have been in nursing for 20 years and in my opinion it is a huge red flag to state that the physical demands of the job are too much. It just does not need to be said. Nursing has become more and more demanding over the years. Employers don't want to hear about weakness, just strength. Keep it short and to the point. Good luck.
