> If only we could flick focus mode like a switch when sitting at a computer, that would be nifty. But you do. When you engage in a task, the dopamine and noradrenaline systems in your brain modulate which parts are active, directing your attention. If these systems don't work well enough, then you get ADHD. If what you mean is to be able to disable involuntary attention control, then that's not good either. You'd be at great risk of under-responding to emerging situations.
