THE touching story of a Sunshine Coast's enduring love through Alzheimer's has captured the hearts of people around the world.
A short video documenting the love of Bill and Glad Forward was filmed and uploaded to YouTube by local short film production group CVCNOW.
It went online on Friday and has so far gathered more than 250,000 views.
Simply titled "What Is Love?" the video tells the story of Bill and Glad, how they met more than 50 years ago and the daily battle with Glad's advance stages of Alzheimer's.
In the video, Bill tells of how he has to do everything for his wife, from the time she gets up until when they go to bed - from brushing her teeth to dressing and feeding her.
"I don't count it a burden whatsoever,'' he says.
"I count it a great privilege to care for this one I have loved all these years.''
The couple, who spent much of their lives working to help lepers and orphans in India and Romania, met through Glad's brother, who was friends with Bill.
He first knew her when she was about eight.
They will celebrate 50 years together this year.
The film stemmed from director Fiona Cameron's desire to tell the story of a couple she has known for 15 years.
"It has been breaking my heart to watch Glad wither away over the last few years but it has also astounded me how Bill has gently cared for her," she told ninemsn.
"It wouldn't cross his mind to do anything but cherish, protect and care for her.''
