"Smartphones were meant to help us be more creative and connected, but they instead became slot machines harvesting our attention.
They flood us with notifications and bright candy colors, severing our brain’s ability to sense if we’re hungry, anxious, or bored.
We even forget to breathe when we look at these bright, addictive screens (‘screen apnea’). We’re lured into wasting hours of our time without noticing it,"
