Like many of Siberia's homeless, Alexei Vergunov survives freezing night-time temperatures of -30 degrees Celsius by sleeping under an industrial heating pipe for warmth.It's a perilous existence. Too far from the pipe and he could die of exposure to the cold. Too close and he could get severe burns without him noticing at first through the haze of hard alcohol that many drink to keep warm and dull reality.
The 46-year-old has lived like this for more than 11 years.
"You sleep at night with your eyes closed but your ears open," he says.
