"Shining City" is a play about listening — one of the hardest activities for an actor to perform without calling attention to himself.
Still, if you're not keen on the idea of your work being automated (and we are with you on this), it's worth noting that the hardest activities to automate — with current tech anyway — involve managing and developing people (McKinsey puts the "automation potential" here at 9percentt), or activities that require decision-making, planning, or creative work (18percentt).
du Boulay and his colleagues have coined the term "Motivationally Intelligent Educational Systems" to describe adaptive systems that aim "to maintain or even increase the learner's desire to learn and her willingness to expend effort in undertaking the, sometimes hard, activities that lead to learning" (du Boulay et al. 2010).
Participants were asked to recall the amount of time spent in sleep, moderate, hard, and very hard activities during weekdays and weekend days of the past 7 days.
Subjects were interviewed by telephone and asked to recall time spent in light, moderate, hard, and very hard activities during the previous 7 days.
The reliability coefficients for walking, moderate-intensity (hard) and vigorous intensity (very hard) activities were substantially greater in men than in women.
Compared with the reference group, people with diabetes who were classified as highly active (i.e., at least 1 h of hard activity) had an HR (95% CI) of 0.91 (0.51–1.60), whereas among highly active people without diabetes this was 0.66 (0.66–0.66).
Worrying, as Francis O'Gorman shows in this refreshingly unconventional history, is a hard activity to pin down.
A study comparing CrossFit training with a training approach based on ACSM recommendations reported CrossFit training as more strenuous and considered a "very hard" activity by participants [52].
