Hi Carapier,
I'm 79 and I still have hot flashes sometimes too. Mine aren't that often but they do show up every so often. I have no idea why they occur or what is causing them. I just drink some ice water and then they go away. I haven't mentioned them to my doctor. They weren't really bothering me that much but still they aren't fun. You would think that since I've been through with menopause for quite a few years the hot flashes would be gone also. I hope your hot flashes go away. Maybe your doctor can prescribe something for you.
Blessings,
PML
