|One of the founders of United States of America Mr. Benjamin Franklin was also ambidextrous.|
Sachin Tendulkar writes with the left hand but batted and bowled with the right hand. Saurabh Ganguli bowled from the right hand and batted from the left hand. Typists, knitters, musicians, etc. use their both hands with equal ease. I use both hands in my daily chores since I suffer from frozen left shoulder.
My doctor told me that left frozen shoulder might have resulted from less use of left hand. Moreover using both hands simultaneously increases my efficiency also but I don’t bother too much about being ambidextrous and do it in symphony with my psych and soul.
