I'd say that because of the kind of work that many here do, the onset isolation/neglect of friendship networks is more obvious than in other occupations. That means people here will notice the situation more quickly and be able to take sensible proportionate steps.

I work as a teacher, so in a normal week I have lots and lots of high bandwidth face to face engagement with hundreds of people. I've seen people retire from teaching and suddenly discover the relative atrophy of their non-work networks, and I'm taking steps to avoid the same experience.
