BobbyG I'm also more tolerant of cold and less of heat, but the heat bothers me mostly when I'm inside, not outside. Is it like that for you?

I'm thinking of an experiment in hopes of building my tolerance for low temperature in my hands since they have become cold in the last two years. Maybe I'll hold some ice for a minute every day or something like that. It worked with my feet a few years ago, though I did that inadvertently.
