Maatru Kaatru. This is a Tamil word which means “alternative air” in English. I don’t know how far it is true. It is said that we can breath this alternative air to improve our health.
For example, someone is taking medical treatment for a long time with no improvement. It is suggested that person go to a different place and take the same medical treatment. At this time, that person is breathing a different air than he is used to. It is said that this alternative air will bring lot of improvement to that person’s health.
I have no personal knowledge. I am just conveying what I have read.
When we come back from vacation, we are relaxed and no longer bored with the daily chores. I am told it is because of breathing a different air during vacation time. By vacation means, you don’t have to go to a far off place. Just a different place than where you live. May be the next town or village.
But it is different in my family. My family thinks unless you board a 747, it is not a vacation.
