That's an assumption. RSS are not as foolish as you think, don't underestimate them....and it IS possible to vastly improve physical and mental characteristics of the baby through improved nutrition, stress reduction etc. if you take away the stuff about "planetary alignments" and such mumbo jumbo, nothing they have said is wrong....in fact in the old days in India pregnant and nursing women were given special food and they were not allowed to do housework and after a certain number of months of pregnancy they were sent home to be with their mothers for extra care and relaxation. This gave the best chance for healthy and smart babies. Nowadays mothers work till they drop their babies on the office floor, I'm sure in the long run this will not be good for the health and well being of future generations.
In fact who knows even the "planetary alignments" stuff, ridiculous as it sounds, may have something. the Chinese use a "conceptions calendar" and I am told that it works...who knows...anything is possible....let's not assume that we know everything there is to know. Our forefathers were not as stupid as we think they were, after all they survived a million years in a harsh world. They couldn't have done that if they were foolish. I only hope we leave a better world for our children as they did for us. I realize this thread was created specifically to laugh at Hindus in general and the rss in particular but actually if you read it fully, they are not wrong, just their way of saying is a little "out of date" shall we say.
