Solitude is a state of seclusion or isolation, i.e., lack of contact with people. It may stem from bad relationships, loss of loved ones, deliberate choice, infectious disease, mental disorders, neurological disorders or circumstances of employment or situation (see castaway).
Loneliness can kill you.
It increase cholesterol, raises your blood pressure, and weakens your immune system. Spend too much time alone and you could literally be shortening your life.
