Again, that might be true of Roman Catholic monasteries. However, Orthodox worship is more “active”. First of all, worshipers stand during services, there are no pews except a handful of chairs for the elderly or infirm. Secondly, monks are expected to sing the sung portions of the liturgy (there is no choir at a monastery, they are the choir) and to perform all of the many genuflections involved. I have occasionally seen 1–2 monks in their dotage being permitted to sit and doze during prayers, but everyone else is expected to remain awake and do everything that needs to be done.
