^^Guys if we keep on following all and everything we read then we will byepass even Baba Ramdev.BTW
,I myself drive for first 3-4 kilometers with windows opened if there is no dust,this removes all the hot gases from the cabin and then A/C is started.
But surely,one must not get too much involved in all these things else we will be forced to wear masks on face,gloves an hands and some more jugaads and will stop driving the car and start riding bicycle.
Also we need to fell ill too,else what will happen to the career of our doctors??
