A Glasgow gran who has been paralysed three times in 20 years is now a a qualified scuba diver, exploring oceans and deep sea wrecks all over the world.
When Margaret Shearer woke up at a friend's house in Miami, Florida on the morning of December 31, 2001, then aged 50, she was paralysed from head to toe.
Medics feared she'd suffered a 'double stroke' and thought they'd found a tumour on her spine.
