57-year-old grandmother Samhun Buthkrua ran up and down the touchline kicking every ball while watching her grandson play in a school sports day match.

Putting in the effort despite not being on the field herself, she gets so swept up in the action that she air-kicks and barks out instructions.

With the temperature reportedly hitting 35C on the day, it’s an impressive display of perseverance from the pensioner.

The game took place in Sisaket, one of the northeastern provinces of Thailand.
