Ways to prevent getting sick?

Hand Washing & Sleep: Hand washing is a good preventative measure as well as getting adequate sleep.

Prevention: Great question! Life is not always fair but we can do a lot to lower the probability of illness by eating a healthy diet, exercising, and getting enough sleep. See a healthcare professional at regular intervals. From a psychological point of view, focus on living in the present moment as much as possible and learn some stress management techniques. Peace and good health.
