Got an update on my uncle's health from my aunt (his sister). He'll be fine, he's just constantly tired and having some bad joint stiffness issues, so he's having trouble doing things and getting around. And despite that he even has plans to go to Thailand in January to see his son. So, fortunately, he's not dying or anything, just dealing with more-frequent-than-normal body aches and fatigue from old age. That's a relief, as I was getting worried that he was terminally ill or something. That's a load off my mind.
