Merlin Mann linked to this comment the late author David Foster Wallace made in 1996(!):

“’Cause the technology is just gonna get better and better and it’s gonna get easier and easier and more and more convenient and more and more pleasurable to sit alone with images on a screen given to us by people who do not love us but want our money and that’s fine in low doses but if it’s the basic main staple of your diet you’re gonna die.” –David Foster Wallace

Prescient.

If what you regularly pump into your consciousness is processed pap prodding you to passiveness—numbing, mindless, turn-off-your-brain-and-scroll-Facebook-or-binge-on-Netflix passiveness—you will die indeed.

Not physical death—though sedentary leads to cemetery quicker—but that kind of junk diet for your mind certainly will kill off some of what makes you an authentic, free-range human being.

Your brain needs to be challenged regularly. You need to more regularly inhabit your physical body and be aware that you are alive—right here, right now.

Read something with substance, something challenging. Be with other humans, really with them. Engage in conversations that provoke and cause pause. Make something. Try expressing yourself more often. Do hard things. Take risks. Inhabit your senses more fully and more intentionally. Go primal. Go back to the basics of what shaped us into the incredible creatures we became.

Live while you can.
