New findings on the way the brain clears waste from cells/neurons finds that the process relies on sleep. I'm assuming they'll be taking an even closer look at the statistics relating to Alzheimers and sleep.
More than just a career involved when sleep is poor. (this is fairly basic, the new findings are about the brain's methods of cleaning where there is no lymphatic system.)
In one study, researchers at the Johns Hopkins Bloomberg School of Public Health in Baltimore found that getting less sleep or sleeping poorly was tied to an increase in brain levels of beta-amyloid, a toxic protein that builds up and forms plaques in the brains of those with Alzheimer’s.

Our country was run by a woman taking four hours sleep a night.
