But work is 40-50 hours of my week. That's a HUGE portion of my life. Almost half my waking hours are at work. (7x16=112 waking hours a week. 35-45% of it at work).
Not taking time to socialize during that period is draining as hell for me. I guess what I'm trying to say is you're way overestimating the percentage of people who can go to work and just... work. Most people need the socialization.
