Many jobs that require high energy output may exceed 60 hours a week. At the low end is the couch potato expending about 6 hours a week. The devout worshiper attending 2 services a week with the average time spent in devotion might attain 30 minutes at the maximum. So, if there is a point here, most people spend more time working out than may actually be healthy for them. Beyond a certain point added physical activity can produce adverse results.
Most people spend too little time utilizing the Creative part of their mental processes.
Most mental activities pursued, even so-called fun activities are not necessarily the healthiest form of mental exercise. Anytime stress is associated with the mental activity it becomes a negative factor. Most people have a mental application deficiency of over a 100 hours a week. If we told someone that we did a Spiritual Workout for 30 minutes every week their laughter would would be uncontrollable.
