Ok I moved to the US from India last year. A little about me ..I am kinda skinny ... was unhealthy skinny when in India but have put on weight a lil now. I cannot bear the cold. Even whenI was in bangalore i could not take it if someone out the fan in the room when the temperature was normal. Hot for others but cold for me. the temperature being about 25 deg C. Now here it is winter. and yesterday i was walking from one building to another in college about 10 mins walk and I felt that I was freezing. This was when im totally covered up. Im wearing thermals, a full sleeves t shirt, a sweater and a huge winter jacket. What do you do to keep yourself warm over here. yesterday's temperature about -20 deg C.
