Love the pictures! You both "were" and "are" a beautiful woman. And, yes, I would love to meet your son (and your daughter, too) if I get the chance.
I did look up "tourmaline sauna" in the Internet, and at least I understand what the device is supposed to do. There are even tourmaline saunas designed just for the feet. My feet are just one of the minor health-related matters I want to resolve this year, if possible. The No. 1 thing I have to fix is this crazy peripheral neuropathy, so I can sleep normally. Once I get that taken care of, I should be able to maintain the weight I want, and increase my mental focus.
