OK so what are you wearing under your work clothes?

[Torchwatch]

The British Polar explorers of the early 20th century had a unique of managing their underwear in the confines of the ship Discovery during the Antarctic winter.

1. Wear underwear for a month.
2. Turn underwear inside out and wear for a month.
3. Turn underwear right way out, wear backwards for a month.
4. Turn underwear inside out, wear backwards for a month.
5. Start again with 1. above.

By this method one always has suitable underwear while sharing the small wardroom with ten other guys for months on end.
