The international day of the ’ciotóg’!

Today is the international day of the 'ciotóg', or left-handed people, known for their creativity, problem-solving skills and unique brain connections.

A new study suggests hand dominance may develop through practice, challenging what we thought we knew about why some of us become lefties and other righties.

Joining John Fardy to discuss is Dr. Natalie Uomini, Scientific Consultant and Editor.
