Just because a chosen work field is how someone makes a living (and by the way, he's no longer raising his grown children), doesn't mean they have to be at it 70 hours/week. Workaholism affects all occupations: lawyers, doctors, retail, restaurant/hotel, airline, mechanics, truck drivers, etc. There's a saying, "If it can't be done in eight hours, you're doing it wrong." The exception would be surgeons who are on-call or making rounds in hospitals, where lives are at stake. But farming? If it can't be done in eight hours, the head of the ranch (whether that's him or not) needs to hire help. If he can't afford it, he's doing something wrong. Sounds like this man is a workaholic, plain and simple. It's a disease and has broken up families. Many studies show workaholism is bad for health. Nobody ever said on their deathbed, "I wish I'd spent more time on the job."
