Warm breeze

These two or three days, it is so warm that I don't have to wear a coat for winter.

But I heard that it must be cold days again in this weekend.

These kind of weather change effects to our health and sometimes weaken it.

Also, warm days, the pollum of ceders starts to fly, typically it starts to fly in march, but the high temperature makes the timing earlier.

So warm days in winter makes me nervous...
