Tito's Mars mission to use WAG bags as a radiation shield.

"The team behind a planned private manned mission to Mars say they've come up with a way to protect voyagers from radiation exposure during the long trip: pack the walls of the spacecraft with a layer of the astronauts' own waste.

"It's a little queasy sounding, but there's no place for that material to go, and it makes great radiation shielding,"
"
