Thanks for sharing that info, GC & D24.
Always be careful with older friends and family members too. Especially when people are already dealing with other health conditions, weakened immune systems, and potential complications with the aforementioned. Things can really escalate quickly. It was one of the things that took my grandpa out in the end in 2006. He had already survived all types of other shit within the prior 5 - 10 years. A fall, colon cancer, dementia, mild heart attack & stroke-type issues. Survived all that ... only for the fall, and broken bone (plus subsequent bed rest), loss of mobility & optimism, heavy bed rest & then pneumonia setting in. Have seen it take out other friends & family too. Have seen plenty more in regards to cancer, heart disease & strokes with loved ones.
