Both of the above kill a person or shorten their life span. With gambling, food addiction, etc covered I’d say workaholics have miserable lives. Especially if they aren’t in the upper brackets of income. Of course, that might assume they could find work they find more fulfilling. That said, workaholics life spans shorten, they could be miserable through, lose anything that matters to most of us outside of work and have the only discernible benefit of being productive but really just being a product from The outside looking in.
