It is cold day.

It is cold day.

They are cold days recently in our place. (It has been really cold recently where I live.)  I live in Okinawa Japan. I like feeling cold. But sometimes I feel get a headache when it is a very cold day. My blood pressure is so high. So I think that it is very relatedionally between the "cold" and the "headache". (So I think that the cold weather and my headache are related to one another.)  

Good Job
