The cold not only makes me stiffen up it also causes depression. Our winters in Canada are long and cold. I agree that if you dress up warm and get outside it does help. It wouldn't be so bad if it only lasted a couple of months but when the temperature gets below 0 Celsius my feet go numb and I don't attempt to stay out for more than 20 or 30 minutes. I can handle the heat much more than the cold.
