I just watched the Late Late Show clip of the teenager, Austin, in Australia, who swam for 4 hours and ran 2kms to save his family that were sweeped put to sea on a paddle board.
I saw his first interview live. The reason why he had to run 2 kms after his 4 hour swim was because nobody on the beach spoke English.
Of course, he was prompted to leave that part out for RTE
