I need a coat with a furnace in it

Lately I run around the house just freezing all the time. I have socks/shoes/undershirt/long sleeved t/sweater (which is wool) and I am still cold. I will not admit that I am getting older and things like this happen to old people. I will layer more clothes if I have to or even add a hat or mittens to the mix. Fashion will be out the window and my comfort not style will trump my situation. How can I be freezing all the time? Is my circulation poor? I am losing weight so maybe I miss my layer of blubber. Who know? Who cares? I do! Need to set more afgans and throws around the house to snuggle up in. Thought even of bringing down my electric blanket and wrapping it around me as I did things around the house but that darn cord would inhibit my work. Oh well, I know I am not dead - heart still beating, I think. I know I can warm up with wool and microfiber on. I need to persevere through this glitch and not cry out for my hotflashes anymore. Man, I am never satisfied with myself when it comes to body temperature. Life goes on!
