Sweating = Exercise?

Today was Field Day.  It was hot (though not as hot as recent days).  Here's my question.  I spent all day standing in the sun on my feet.  I didn't really run (the kids did!), so I don't know that I can argue that I was actually exercising.  Do you actually burn calories by standing in the sun and sweating?  It really wears you out.  I am exhausted tonight!  If you don't, that's totally unfair.  If I'm going to be as worn out as I am, I should have at least burned some calories.

I've been terrible about my daily blogging.  I've had a lot going on after work, and when I get home I haven't been in the mood to blog.  At any rate, here's 3 days of menus.
