To those who meet him, Kyle Goodwin looks like a perfectly healthy and fit young man.

But inside the former Byron Bay tradie’s lungs he is carrying a potential death sentence.

Six months ago, Mr Goodwin, 33, was diagnosed with accelerated silicosis, an irreversible lung disease caused by exposure to silica dust.

Mr Goodwin’s fate was sealed during the eight years he worked as a stonemason cutting up kitchen bench tops.
