how about a hint?
I just wondered about something different.
*** They found that 12.8 percent of male musicians and 11.8 percent of female musicians were left-handed. The rate of left-handedness in musicians was significantly higher than in the control volunteers. In this group, 8.5 percent of males and 7.3 percent of females were left-handed. Thus, being a professional musician is associated with a modest increase in left-handedness.***
From the article.
I’ve played a guitar my whole life and never noticed more than the the average of lefties playing. Never been a professional, but played with many, many people through the years. Not dissing anyone, I have 4 south paws in my immediate family.
