Grandmother Kathleen Connell has sworn that her Nintendo DS is what has helped to keep her mind fresh despite reaching the age of 100.

Speaking to The Telegraph Kathleen said that she plays several brain training games every day with game sessions before bed.

She isn’t sticking to the one game either, Kathleen owns over 12 DS games made to keep your brain in check. Brain Training, Art Academy and Scrabble are just a few of her personal favourites.

“I much prefer to be using my brain. And I find I am very forgetful, I can’t remember things the next day. So I try to do these and it really is helping,” Kathleen said.

She added that “she doesn’t feel a day over 80″ and that “she doesn’t know what she’d do without it”.

Kathleen Connell we salute you.
