With the advent of central heating, hot water and food abundance, modern man has forgotten how to protect the immune system effectively from seasonal bugs including coughs, colds and flu.
How did our ancestors survive?
With this question, I am not suggesting for one minute that we all go back several hundred years! I too love my home comforts. The question is more about building immune health to live in our populated cities and towns as well as when commuting and travelling on trains, planes and in other forms of transport that can be rife with any seasonal bug that might be going around.
