This article is totally in contrast to what is seen in my family. I have a brother who is younger to me by 6 years. However, if u compare our IQs, well, the lesser said the better. He is currently working as a consultant in a leading software MNC at age 23 after completing his Engg in Elec. & Telecom & his pay is above what I'm earning after about 3.5 years of service in the Biotech industry. My knowledge is limited to my field of interest while he is an ace in Astrophysics, Science in general, Biology, Biotechnology & even politics....Now if that isn't an exception to this study, what is??? Cheers. Vineetha.
