What do you think rots your mind and what doesnt?

Question:

what are ways that we can improve ourselves and get smarter? what are ways that we just utterly waste our lives upon?

Answers:
Challenge keeps the brain active and sharper than routine.All news media rots the brain because they make the most money with negative stuff (via advertisement)so they are bias toward it.Positive stories and comedy keep the mind positive.
Physical activity keeps the mind healthy,Geeks that work out are way more upbeat than the potato's..Reading makes you smarter so does learning simple things like camping and fishing. Trying to avoid discomfort and seek only personal pleasure are a waste.Narcissism leads to loneliness.

Watching Fox News, in particular the O'Reilly Factor, will rot your brain. So will Sponge Bob.
