Manfred Spitzer is a german neuroscientist and psychiatrist who's written a book on digital dementia, called just like that. I've just watched some 3 hours clips of him explaining the main book ideas, and in conclusion, our brains are not computers, they don't crash, but they do downgrade.

80% less brain matter in a functional man

If we're not working on our memory, if we choose to externalize the mental effort, we're not having more space for other mental things, like more space on a hard disk, we're actually putting ourselves at a great risk of Alzheimer and a faster brain downgrade. Besides living with a slow brain...

He admits it's impossible in today's world to do your work without digital devices, screens and platforms, but advices we should exercise our memory (adults but especially children and teenagers). So this is an article to remind myself also I should:  

  • learn new dances (it's both memory exercising as well as movement)
  • learn to play musical instruments (piano helps the brain develop the good kind of multi-tasking skills)
  • learn new languages (could also be financially rewarding)
  • learn jokes and games (you'll be more fun at parties :D)
  • learn poems, songs (and other good things for your soul) etc.

Reading from digital devices increases the risk of myopia (again, especially in children and teenagers) so print if you can. 

And if you want to be smarter, make faster connections, learn things more easily, exercise your memory muscle like you would your other body muscles if you were to prepare for a fitness championship. I know I'll try to.
