80-year Harvard study has been showing how to live a healthy and happy life
What I take from this article is that social interaction is extremely important to ones health, and it's something that we largely taken for granted.  In the age of computers and secluded work environments, I think we need to be aware of the effect that even casual interaction has on our mental and physical health.  I have some personal/anecdotal experience which back this research up and affirms my belief that communication and interaction with others is vital.I've been working from home for a number of years.  During this time I've on average spoken with and interacted with 1 person every day - my wife.I occasionally go out, occasionally see family members, but the majority of my day-to-day work is quiet, alone, working at a computer.-  I have been more sick in recent years than ever before in my life.  This is even compared to previously living in a major city and taking public transportation.-  I have been experiencing sharp mental decline especially in the last year.  Solving complex problems is much more challenging.-  My memory is suffering.  Even my wife has begun to notice, I forget little things and have developed an "aloof professor" disposition that wasn't natural to me.-  I now find social interaction more difficult.  I'm more akward, and find myself over-thinking previously natural interactions.-  Lastly ... I'm far more depressed.  I just don't enjoy much these days.  I wake up, work, don't talk to many people.The TLDR here is that I urge everyone to tend to their social garden.  I let mine decay for too long, and I'm paying the price now.  I am beginning the process of restoring connections, and getting out more, and I'm already noticing an improved mood.Oh and I should mention - I'm naturally an introvert so this reclusive lifestyle was all too comfortable for me.
