Too old for cold

Have you noticed that children don't seem to feel the cold?  Parents nag about wearing coats, they buy hats and gloves, and kids discard them on the playgrounds.  Visiting at my mother's a couple of weeks ago, it was cool outside.  My young nieces would put coats on their children, only to pick them up off the lawn later.  The children didn't think it was uncomfortably cold. I had on two t-shirts and a jacket--I thought it was.  I have had students whose winter coats (and this is northern Utah--we hosted the winter Olympics) were sweatshirts (hoodies).  

Maybe something happens to our metabolism, maybe our brains finish developing, maybe age creates a shrinking comfort zone.  Whatever.  Sometime along the way we begin to feel the cold and choose to dress accordingly.  Personally, I am part lizard.  Anyone who knows me knows that if I am warm, it is warm!  I don't get properly comfortable until about 77 degrees, I never wear short sleeves before mid-June, and I don't complain about the heat. In fact, I think I'll go outside and soak up some sunshine now (but not without a little sunscreen for my skin).
