This Colombian couple, former drug addict, Miguel Restrepo (62 years) and his wife, Maria Garcia, have lived in the sewer system, under the streets of Medellin, for the past 22 years. Their home is 6 square meters and has one window in the ceiling, with no glass, which means that when it rains, there bed gets drenched.
and after 22 years, i'm sure they've figured out some way of dealing with the rain problem. i'm picturing a large umbrella opened on top of the hole, with a weight on the handle to keep it stable.
