The second semester of this period will be much calmer than the first, and it will once again bring certain adjustments into Sagittarians lives. Nobody is likely to deliberately create a situation which can be characterized as a risk to your health. However, circumstances wont always be on your side, so you would do better to avoid going out into the cold without a cap, or running outside from the gym without cleaning yourself or drying yourself. A slight breeze could easily be enough to give you a cold, no immune system is safe from this, although Sagittarians are unlikely to have any difficulties with their immune systems in 2018. So pay attention more often not to yourself, but to your environment, because it could become a source of potential danger. Unfortunately, you will definitely face situations where someone from your household gets sick. During this time you would do best to stay far away from home, otherwise youll also risk falling ill. Fortunately, this period is unlikely to last long, and aside from that, all of this will be a once off occurrence and not a trend.
