Maybe it isn't "advice", but it is subjective interpretation, since the results are an interpretation of a single study. Nor does the study appear to account for other factors, such as physical constraints.

Obviously, in my particular case, I can't physically write for more than a few minutes at a time.

And quite frankly, my handwriting has degraded to the point where it's barely legible even to myself unless I place a rather exhausting amount of effort into it.
