To a greater or lesser degree?
Irrespective of the reason why (war or zombies or plague or whatever) if there was only a very brittle skeleton of society and the safety nets left, how would you do?
As a person dependent on medication for survival I'd be fooked pretty fast. What I find interesting is, maybe if I was a different type of person I might be ok despite needing medication - but my personality just isn't wired for that sort of situation. Introverted, would be completely drained living in a group, just would want to run away from any sort of 'leader' type.
Whereas some people would probably thrive in a group dynamic, being constantly around people all the time, earnestly bossing folk around who they didn't think were taking the chores seriously enough.
Would your cope well with all the politics and trying to rebuild a better society?
