Ok fair enough, for social interactions, board games would probably be better than video games but perhaps they are more introverted than OP.

I'm sure OP has good intentions but as others have said you can't push your vision of healthy living on others, they have to come to that conclusion themselves. Apparantly these friends are smart so likely know the health effects of a sedentry lifestyle and that's their choice.

The tone of writing is quite condescending pretending those of us that have jobs or other hobbies live in some kind of work-happy socially integrated utopia.
