One out three will develop some form of dementia. I have two sisters with it and I am very thankful that I missed it; I can still enjoy some aspects of living with my health issues...
I don't believe in statistics that are based on things that haven't even happened yet. To say one in three in this town developed some form of dementia is measurable, but to say one in three WILL develop it is just negative thinking and I won't go there. No one can predict the future, so why be miserable listening to those who think they can?
I'm glad it missed you!
As to the original thread theme of bravery and age, I thought about this a couple of hours ago, when looking under a friend's hood to see if I could find the source of her car's noise. It's a full-size sedan, with a heavy hood, and as I felt for the hood release I thought a lot about getting my fingers stuck, or, if I were able to lift the hood, it crashing back down on me. I never worried about stuff like that before. Of course, my cars all had prop rods for their hoods, but none of the cars I grew up with did, they didn't even have hood releases inside the car. I don't worry these days about someone popping my hood and stealing the battery or sabotaging the engine, but today I found myself worrying about getting my fingers stuck or crushed.
But I didn't let it stop me from lifting the hood and finding the source of the noise.
Now, reckless is going shopping with one of the two neighbors who will drive me places but is just as apt to have been drinking as smoking when she gets behind the wheel, or tailgating the car of some driver she believes has cut her off or been otherwise rude. She is otherwise a good driver and has never had a wreck; she is more likely to get pulled over for a breathalyzer than to be in a wreck. If I know she's been drinking before I get in the car with her, I don't. But if I find out after the fact, I go ahead and hope we'll get home safe, because I can't afford to be stranded away from home and have to depend on undependable Uber to "rescue" me.
So that's not bravery, it's recklessness. Doing what I have to, to get by.
