I know some older (menopausal) women who are always warm, never wear sweaters in winter and are comfortable in over-air-conditioned buildings in summer. I'm generally colder overall now than I used to be, especially my extremities. Ten years ago I would be comfortable in lightweight tights when cycling in cool weather but now I need heavier tights and booties or toe covers in the same conditions. As he's gotten older, my 81-year-old father feels the cold more than most people, and his mother was the same way. I seem to be headed down the same path. But at the same time, I was extremely uncomfortable working out at my gym this winter because it felt way overheated to me, to the point where I started using the small fitness center at my office instead, while no one else at my gym seemed the least bit uncomfortable. And I've always had more problems cycling in the hot summer sun than my friends -- I'm always the one who needs to stop in the shade to cool down.

So I guess there's no clear pattern for me, at least not yet.
