as for staying cool? In Oklahoma, here is the entire summer

1. wake up in air conditioning
2. get ready for the day in air conditioning
3. Run to car and turn on air conditioning
4. drive wherever you are going
5. run from car to house/store/building with air conditioning
6. repeat steps 4 and 5 until the day is over
7. drive home in air conditioned car
8. run from car to house with air conditioning
9. go to sleep in air conditioning
10. go to #1 when you wake up.

* if you have a choice to go to either hell or a destination in Oklahoma without air conditioning, choose hell. It will be cooler there.
