Exactly. But it was only when I entered the workforce full-time that I truly appreciated Shabbat. Especially in a world when I am expected to be on-call 24 hours a day, I honestly cannot understand how people do without a real break once a week. On a personal level, it can't be healthy to constantly be on, 24/7, practically 365 days/year - and translated to a musing of more general applicability, that might lead to better / more productive business. Perhaps a worthy subject for experimentation by businesses (more than what some banks have done recently for summer interns and junior analysts).
