Well, my mother in law has alzheimers...she does not have diabetes, high cholesterol, or hypertension...and she has never smoked. At 73, she still walks 3 miles a day, swims 30 laps in the pool and plays a mean game of golf (ok, she needs someone to keep track of her ball, so she doesn't forget), even as her mind deteriorates. I hate these articles that say, "if you do this/have this/...you'll get this disease". We're all gonna die of something. Life life to the fullest, take care of yourself, pray and hope for the best.
This article mixes Alzheimer's and dementia. They are two different conditions. Very poor reporting.
