Attention is evolutionarily designed to move toward the highest opportunity (food, valuable resources) or the highest perceived threat in the environment, automatically concentrating all mental resources on that target, which was adaptive for hunter-gatherer survival but creates vulnerability to modern attentional hijacking by devices.

Mindfulness and meditation balance the attention-capturing effects of modern devices by quieting the mind and allowing people to 'be at home in your body,' which fades distraction and allows access to the underlying happiness the ancient Greeks called eudaimonia.
