If it had not have been for that awareness poster the doctors confirmed Mark would have died at home in bed within a few hours.
Mark had contracted meningococcal meningitis and septicaemia.
As you can imagine this left all of our family in a state of shock and anger because Mark was there one day and 24 hours later we was told he was brain dead.
But my mum and dad, although going through all this, still agreed to donate Mark's organs and he saved the life of 3 people.
