>>33406085/adv/ expert here. Yes, there is merit to the idea of a dopamine detox.
>>33406021 is being obtuse. The "detox" part is metaphorical.
You can accustom yourself to cheap tricks, easy dopamine, instant gratification. Things like porn, fast food, forums, video games, are supernormal stimuli, that is, a stimulus which engages with the reward system MORESO than what our reward system evolved for. 10000 years ago you saw maybe 15 women in your entire life, and your recreational activities were limited to wrestling with your boys and throwing shit at trees. Now you wake up and immediately are inundated with more intense stimulation in 45 seconds than all your ancestors combined did in their entire lives, all of it coming from a little rectangle that you sleep with next to your cushy bed.
Yes our reward system adapts to whatever lifestyle we feed our brain, yes if you goon all the time and play world of warcraft for 6 hours a day you will be less sharp, less perceptually ready, more tired, will have more difficulty concentrating, planning, thinking, etc., than someone who hikes and works out and is very strict about what they consume, and does shit like research and read long books in his spare time.
During which context would you find it easier to sit down and read a book for an extended length of time without becoming distracted? In a room with a bed, bookshelf, and chair, OR in a room with a bed, bookshelf, chair, computer table, computer, iPad, iPhone?
If you are deprived of the absolutely surreal amount of frenetic bullshit stimulation you are so accustomed to for long enough, boring ass shit like reading philosophy suddenly becomes very interesting.
