After spending most of my time up in Globe, coming down to Phoenix feels like voluntarily climbing into a heated pizza oven.   Temperatures have been below normal and I still bake!  But the Phoenix house won't paint itself; I asked. 

If you're like me, after a few hours outside, you wilt.  For rehydration, you can slug down some Gatorade or Powerade - or you can go natural.

The following is my favorite summertime picker-upper.

Mix up a batch of orange juice with calcium and chill it.  When you need a drink, pour a half glass of orange juice and top it off with cold club soda.

The drink is festive and the club soda adds tang while diluting the orange juice enough to allow rapid  absorption of its nutrients.  (Undiluted orange juice contains too much sugar; you should not drink it when you are hot.)
