My uncle stayed functional and active until he was 85, but what actually killed him was his fear of an oxygen mask he needed to treat COPD. That fear, and a fear of strangers were the chief manifestation of his alzheimers. (which his daughter said he had but I'm not sure he did) The hospital inserted a mainline to put him to sleep so he could have oxygen, and he ended up with MRSA I think- within 2 months they had managed to kill him. I was in town to visit, we'd had a great lunch, driven around seen the sights, sat and reminisced, one of my daughters and her husband and child were with me, had a wonderful long day. He woke up with difficulty breathing the next morning. I was sleeping off jet lag, his wife took him to the hospital, and I never saw him conscious again. We forgot to take pictures that first day, we had so much fun. Do I think he had alzheimers - no. But both his parents had some degree of early senility, they died at 80. He made it to 85, my father was dead at 55, but not hereditary stuff. so I just don't plan on hitting 100 and I keep busy. Being on this forum is part of it. Facebook is boring. My work is so challenging I couldn't it if I was "normal" (think 8-5 mentality). No way I could do it with Alzheimers active. I've got a couple hundred customers and lots memorized, from the size, appearance of their pond to how to get to their house. I have only recently even started using GPS. And I drive a LONG way. I also take turmeric paste. They don't have a lot of alzheimers where they eat a lot of curry.
