It’s every year the same: as soon as the winter starts to arrive there is a massive cold and flu outbreak. It begins slowly, when you notice here and there that someone is coughing and sniffling. But before you even realize that the virus is spreading, everyone around you is sick. What makes things even worse is that you cannot hide from it. You can take all precautionary measures one can think of, only to wake up one day with a sore throat. It’s that moment when you realize that the common cold has caught you, once again. And quite frankly, it is an uncomfortable feeling. One feels helplessly exposed without a chance of fighting against the virus. Some years ago, it was so bad that I felt like I was part of a vicious lottery that decided by chance how many colds I would catch throughout the winter. Nothing seemed to help; there was no escape from it. That was the moment when I decided to take a stand against it. I began to study people who never seemed to get sick. Above the surface line, they did not do anything different. Below the line, however, each and every one of them had a habit (knowingly or unknowingly) that allowed them to maintain good health. And I started digging for exactly these habits. My curiosity was rewarded and I began to uncover one gem after another. Some methods were rather unconventional. Others seemed to defy any logic, but some were hidden in plain sight. Throughout my research, I was constantly motivated by one single thought: if those people could prevent a cold with a single method, combining these various methods would be even more effective in preventing colds. Better yet, it would provide results for the common person as well, not just for those whose immune system works above average.
