A joke about Alzheimer’s disease was tweeted on July 14, 2020 and probably originated on the Sickipedia website:
   
“They now say exercising for at least one hour a week can half your chances of getting Alzheimer’s. I’ve just got to remember to do it.”
 
     
Wikipedia: Alzheimer’s disease
Alzheimer’s disease (AD), also referred to simply as Alzheimer’s, is a chronic neurodegenerative disease that usually starts slowly and gradually worsens over time. It is the cause of 60–70% of cases of dementia. The most common early symptom is difficulty in remembering recent events. As the disease advances, symptoms can include problems with language, disorientation (including easily getting lost), mood swings, loss of motivation, not managing self-care, and behavioural issues.
