Kelli, it is probably partly genetics and partly that I have adjusted to a much hotter range of temps. I remember my mother always being cold when she was the age I am now. I'd go to visit her in Santa Barbara from San Francisco and it would seem really warm and temperate to me but she would be sitting in front of the fireplace with a blanket on her shoulders. I couldn't even walk into the bathroom when she was showering because first of all she would yell at me for letting in the cold air and second it felt to me like there wasn't any air at all in there just heat and humidity. I have her super low blood pressure as well so that may contribute to it.
