- Smoking feels good but doesn't provide any useful function.
- Some social media use feels good and doesn't provide any useful function, but social media is extremely useful to cheaply keep in touch with friends and family and extremely useful for discovering and coordinating events.
Fortunately the "keep in touch" part can be done with apps that don't have so much of the "social media" part, like Telegram, Discord, and even Facebook Messenger versus the main app.
