Take a shot at the sun with your laser gun

It's pretty summery out there. Y'know, warm and stuff. There's been some rain in the last few weeks, but it hasn't been cold at all. Humid occasionally, but hardly chilly.

I understand that colds happen in warm seasons, too. Summer colds can be really nasty, and it's not very much to do with the weather. I haven't had one, but I understand that winter complaints can sometimes spill over into summer.

However, I would really like to know why the blithering hell I am developing chillblains.
