What was once a very natural human function which our ancestors did naturally just by living has become so illusive that we have whole industries dedicated to providing us with the ability to force ourselves to exercise. Our society has now been shaped so much that most of us don't get sufficient natural exercise and we have to join workout clubs and gyms to try and stay in reasonable shape, and those that don't gradually slip in to an unhealthy physical and mental condition and the majority of us become overweight or obese.
We have gone from a life where walking, climbing, crawling, lifting, running, and other natural exercises were a big part of our everyday lives to one where we do anything to avoid exercise. We travel everywhere in our cars, we sit at our office desks most of the day, and we use elevators, escalators, and moving walkways everywhere to avoid physical effort. At home we sit in front of our TVs for most of the time while our kids play video games instead of playing outside or exploring in the wilderness.
Much of this has come about because our incredibly hectic lives mean that even a simple small walk from A to B is replaced with a trip in the car just to save those valuable 10 minutes in our day. It has become the norm that natural exercise of any form is considered to be a chore or some irritating inconvenience that we should find a way to replace with something less strenuous to avoid moving our bodies.
In Nutopia free time is significantly more available because all the aspects of our crazy lives today which gave us so little free time are not present. People don't work long days and long hours or have multiple jobs because they have to in order to survive. Work is carried out by all people fairly and only work needed by the community is carried out so people typically only work a few hours a day for a few days a week. People also work on Tasks instead of working the same job all the time so instead of sitting in an office chair for the entire week, someone might be working a variety of different physical and mental tasks as their labor contribution during the week. People don't use up their valuable spare time after work doing chores because all the work needed to keep the community functioning as a whole is shared equally and fairly by everybody.
Natural exercise such as from walking, running, hiking, sports, and numerous other leisure activities are widely and easily accessible in Nutopia. Because of the easy access, the convenience of the transportation system, and the fact that people aren't exhausted from a long day commuting to and from the office and working all day, people tend to spend more time with other people enjoying physical activities rather than collapsing on the sofa and watching TV. People use the Path Network on foot or bicycle to travel locally because it is an enjoyable experience and there is no need to rush anywhere.
Regular Health Checkups are carried out on all citizens every 3 months and their physical condition is monitored. If a person's physical health is not within certain thresholds then the Guardian System will adjust their access to certain activities. For example a child who has poor physical health due to lack of exercise will be limited to a certain amount of non-physical entertainment such as video games and TV. Similarly an adult might be limited to traveling on the Path Network using physical effort rather than using the Under Ground Pod Network for certain trips.
