Thank you for the interesting feedback! I think I'll need to make it harder to be sick... Unless you're very very fat, taking a walk a day and working once as an acrobat should be enough to maintain an ok health. Then, buying more comfortable housing will also help, and getting into government and taking some planetfriendly decisions can for example make the city air cleaner so you'll indirectly decrease chances to get sick on the long run (it can take a few years before the effects start to be interesting, but nothing will really tell you except for the city pollution indicator in city stats).
Lots of things have been added since when the guide was written, I hope you find a bunch of fun features ! I'm glad you like the game, even unfinished! <3
