Much depended on a person's financial and social standing. You could obviosuly lead a more comfortable life as a wealthy noble than as a mere worksman. For those not fortunate enough to be born an aristocrat, there were a number of possible lines of work. Many people would go out of town to cultivate land, others became members of various guilds uniting craftsmen of respective kinds. Paying a membership fee meant that in case of an accident that would make you unfit to work you and your family would be covered for by the guild. Other popular professions included a clergyman, peddler, merchant, tradesman etc.
Usually once a week there was a market fair and a bigger one was organised once or twice a year. Townspeople would gather to sell goods and buy products from distant lands, but also to watch artistic performances and enjoy themselves. 
  As most buildings were made of wood and not stone the people had to face the constant danger of fires. Access to fresh water would be limited if it wasn't for nearby streams and rivers, but that also meant that floodings were a common occurence.
