Genetic researchers at SNU announced yesterday that they had discovered a gene that is common among the Korean population. Roughly 25% of Koreans carry this gene, tentatively named S.U.B. (Shrek Under Bridge). Those who have the gene feel an inexplicable need to remain in shade, preferable shade generated by large concrete or rock structures.
Vestiges of this behavior can be seen in the huge number of Koreans who enjoy gathering under bridges throughout the warmer months. Interestingly, some researchers have pointed out that these "Bridge Sitters" seem to remain under the bridges even after the sun has set. One scientist hypothesized that that was largely due to the sedentary effects of a daylong soju party.
