I know, I know it is so cold outside and if your car is broken you simply don’t know the way out since going to work on your own seems to be a real cold torture. But, everything is not that bad since doctors claim – in order to stay safe and sound and to avoid flu you HAVE to make at least one short walk a day. Actually, it doesn’t matter how cold the weather outside is. During such a walk you allow your lungs to breathe and inhale much-needed fresh air.
