"...Based on this, if you are at risk for Alzheimers (your 23andme report shows this), then one of the most important things you can do today is to religiously track your sleep and make sure you get enough deep sleep daily."

Getting enough deep sleep is probably good general advice anyway, but it's as-yet unclear if Alzheimer's or amyloid-β plaque buildup is caused by poor sleep; or if a third condition causes both poor sleep and amyloid-β buildup, in which case addressing the underlying cause is what will help, not religiously tracking sleep. Not enough information to say, yet.

But, yes, everyone get a good night's sleep!
