Here’s a personal observation that I would like to share: I typically have a ‘messy’ way of going about my day, which over time affects my brain health.  In the morning I wake up and I check my emails, go on Facebook, see the latest news on CNN.com etc..  Throughout the entire day I constantly check emails on my phone.  When I sit down at the dinner table I watch YouTube videos on my computer.  If I’m with a friend(which is rare) and a topic of interest comes up I’ll Google the subject as we speak.  In between flights I’ll check the latest Dow Jones numbers, recent Donald Trump shenanigans, the 12 foods you must avoid, actors from the 1980’s and where they are now etc. etc.  At night I again go to YouTube and watch random videos that are suggested and/or of interest to me until the wee hours of the morning.  I’ve personally found that this type of behaviour (or ‘behavior’ for American readers) is quite taxing on my mind.  On the other hand when I consciously choose to schedule a set time and duration to go on the Internet and check emails I don’t randomly go from one website to another, I get more done during the day, my mind doesn’t feel ‘stuffy’ and at the end of the week I’m not as exhausted like I often do.  Just my observation.
