I agree with most of your advice, especially "go outside" ... but I don't understand why one should "stop listening to podcasts". Do you mean stop listening to podcasts which discuss current events? Because there are plenty of good podcasts which don't.
Also, I think this is good advice even without the proliferation of deepfakes or GPT spam. I already abandoned social media in favor of small group chats and Real Life long ago, and I know I'm not alone. The only habit I still need to kick is reading too much HN. ;)
