You become used to it in a few months or a year. Moreover, the winters in US don't have to be spent like in India where you are cold all the time even in your homes. In US, the houses are heated, so even if it is -30C outside, the houses are close to 25C inside. So, you can wear a T-shirt and still be comfortable.
I like to blog about various topics ranging from education in IITs to social issues in India and US. All opinions and views presented here are my own and not of my employer.
