A few years ago, psychologist Sheldon Cohen conducted an experiment. First, he asked adults a key question about their childhoods. Then, he squirted cold viruses up their noses and watched his subjects for several days to see which of them got sick.
As it turned out, the answer the adults gave to that question was "a great predictor" of whether they would develop the sniffles, says Cohen, a professor at Carnegie Mellon University.
This is pretty bizarre.
Did your parents own their home when you were a kid? Actually, Cohen asked that question once for every year from birth to age 18 and found that "the more years your parents owned their own home, the less likely you were to develop a cold,"
Does a double wide count?
