Hanna Fraser, 72, took her taekwondo test to join her daughter and granddaughter

Hanna Fraser took up martial arts after a heart attack in 2012. She says attitude matters more than age when it comes to her success.

Hanna Fraser is a 72-year-old Halifax grandmother who can snap a board in two with the palm of her hand.

And that's just one of the tasks she'll have to do during her black belt test on Saturday. If she passes, she'll join her daughter, granddaughter, son-in-law and grandson in wearing a black belt.
