Suitable for activities that require very intense concentration, and where the locus of attention is external, e.g. attending lectures, emergency briefings, learning in a classroom/auditorium context, problem solving with time constraint, and others.

Energize you for emergency situations, fast-paced time-based competitions, high intensity activities where you need to be.

Best for situations that require an external locus of attention, e.g attending group discussion, lectures, seminars, talks.
