From the start, the article equates "concentration" and "mindfulness", with no backing for that assertion.<p>From everything I've heard, they are <i>not</i> the same thing. Concentrating on a crime scene you are not present at, for example, would mean your mind is not focused on the here and now -- in other words, concentration of the kind they're speaking of seems to be the <i>exact opposite</i> of mindfulness.
TLDR: There is no need for pointless agitation.<p>Solve your problems the Feynman way:
1) think about the problem really hard
2) write down the solution
<i>"These effects make sense: the core of mindfulness is the ability to pay attention. That’s exactly what Holmes does when he taps together the tips of his fingers, or exhales a fine cloud of smoke. He is centering his attention on a single element. And somehow, despite the seeming pause in activity, he emerges, time and time again, far ahead of his energetic colleagues."</i><p>I'm not sure I trust scientific conclusions drawn from the behavior of a fictional character.
