Also, I've read how she is very fit in other articles, and here it reinforces that by saying she's been a member of the Curves fitness gym for six years.

This may jibe with the article above regarding what shoes Helen may be wearing. I assume they mean those shoes have been located at her home and not while out searching for her, so they are not a clue to her whereabouts.
It happens so often, that someone suffering with Alzheimer's wanders and gets lost. One one hand, it's so wonderful Helen is in great physical shape to be able to walk long distances, but with her mentally confused state, it creates an added worry since she can keep walking and get a long distance away from home. I wonder if the husband just dozed off after lunch, and Helen decided to go for a walk. Easy to see that happening. I'm younger than them, but find the need to nap sometimes, too!!
