My Thai wife in her bedroom not minding 29 C (84F)

Generally I have not put much credibility on theories of racial differences for thermal comfort. My Thai wife's comments, sweat thresholds, and complaints are very close to my own. But as the hot season closes this year in I notice that I am turning on the aircon every night when the temp hits about 29 C (84F). She is not. Be interesting to see when she does.
