I was like that as a child. As an adult, I’m always hot, unable to live without air conditioning, always looking forward to cooling down with a swim or a cold shower. (And I live in Canada; it’s not like the ambient temperature is all that high!)

Maybe I was that way as a child as well, and just wasn’t introspective enough to notice.

As an adult, I do get cold eventually, though; I can’t stay in cold water for hours, like I could as a child.
