You likely will lose the first two categories that Aristotle mentions and will need something to do to fill your time.
Aristotle believes that there are three different kinds of friendship; that of utility, friendship of pleasure, and virtuous friendship.
But I bet your doctor has no protocol to get you back into social connections or volunteering.
Method: Data from the Health and Retirement Study (2006-2010) were employed. Two measures of social engagement, volunteering and informal helping, along with two measures of social participation, attendance at religious services and social group meetings, were included. Mediation models for health behaviors were estimated.
Results: Multinomial logistic regression models demonstrated that volunteering provided the most consistent results in terms of a lower risk of incident CVD and mortality. Furthermore, volunteering at higher time commitments is related to lower CVD incidence and death; informally helping others at a modest time commitment is related to lower risk of death only. Health behaviors mediated the relationships. Social participation was not related to either CVD or mortality.
Discussion: Social activity is a modifiable behavior that may be considered a potential health intervention.
