Yoshio Kinoshita is living proof that you can teach an old dog new tricks.

The 81-year-old rides the ramps at his local skate park in the city of Osaka almost every morning, picking up tips from skateboarders decades younger than him.

"They are all my teachers," said Kinoshita, who worked as a technician in the construction industry before retiring and still works part time as an attendant in a bicycle parking lot.
