Lately, hot weather become a major trend in Plurk and probably in other social networking sites as well. Many people said that the weather has become hotter than usual. I did feel it and i think it's one of the reason why i got sick two days ago.
Today, the weather has become better, but it's still not the normal weather i used to have in the past. It's still considered hot, but the temperature has decreased compared to yesterday.
Any ideas why this is happening?
