Summer?

Personally, I don't think summer is for me. Even as a little boy, I enjoyed cooler temperatures more and my body and mind don't like the heat. Strangely enough, I get colds more often in the summer than in the winter and in the winter I have a lot more energy to enjoy myself. I'm happy when the weather is colder. I don't like summer in general, as I said, because I sweat, get sluggish and get colds more often and, above all, I can hardly fall asleep in the summer. Sure, I like going out in the sun, but not when it's so warm. So I'm more of an autumn/winter person. What's wrong with me? Everyone really looks forward to summer, but not me, and above all I wonder why my body reacts so badly to heat.
