Latest Research on why we are gay
 

Dr Safiul Azam, associate professor of Sociology at Dhaka University, went on to say homosexuality was increasing at the rate of 3.5 percent a year (in Dhaka).

Dr Azam's explanation for this was arsenic contamination of the drinking water supply.

"With a steady injection of arsenic in their blood stream over a week, 94 percent of African mice invariably lost the ability to distinguish between cheese on mouse traps and those on plain white paper."

The connection between cheese discernment in mice and homosexuality was apparently too obvious to explain.
