Wouldn't it be great, considering how many of us are overweight, if carrying a few extra pounds meant we'd live longer?

Though increasingly common, Alzheimer's disease still isn't all that easy to diagnose, especially in its early stages.
Forgetfulness and other signs of dementia can be caused by lots of things other than Alzheimer's. Sometimes the symptoms are fleeting or normal in the context of a person's age. But at other times these symptoms mark the dark path of Alzheimer's.
