Theories on both sides of the Copenhagen-Malmo bridge

Bold theories have arisen on each side of the bridge [see image below] that joins Copenhagen, Denmark and Malmo, Sweden.

In Copenhagen, a new theory that rising carbon dioxide concentration in the atmosphere has caused an increase in the percentage of humans who are obese.

In Malmo, the theory a few years ago that putting heels on shoes gave rise to schizophrenia.

(Thanks to investigator Gary Dryfoos for bringing the carbon dioxide theory to our attention.)
