A teacher who lost the ability to walk, talk and care for himself gave one last incredible lecture. Paul Norman, 58, was diagnosed with Multiple System Atrophy in 2012 forcing him to retire from his job as an English teacher.

His son Will, 22, began filming his every day life, eventually taking him back to Billericay School, Essex, where he taught English for 15 years.

Paul delivered an inspiring final assembly to a packed hall of his former students, written on his iPad and played out on a speaker.

He told his audience of his devastating struggle with his condition, even making them laugh with jokes about his "Stephen Hawking" voice.

He passed away ten months later, in April last year, before film and English student Will had finished the documentary 'One Last Lecture', featuring the scene.

Much to Will's regret, his father never got to see the completed film, which has been watched thousands of times since it was published online last month.

Will started making the film in July 2014 after he visited his father from Billericay, Essex, and found he was wheelchair bound.>He choked on a piece of rice, forcing Will to perform the Heimlich manoeuvre to save his life, and he went back to his university that night and "broke down".>University of Sussex student Will explained:

The pair grew close and for the first time Will saw the reality of his dad's every day struggles. They gathered an assembly of former students and staff, and wrote the speech together>Final year student Will added:

He completed filming in the summer of 2015, before Paul passed away in April last year, and he completed the movie in mid-January this year.
