Other than 6 hours in the morning (5:30 am - 10:30 am), it is just too damn hot for me in the afternoon. I get all my gardening chores, watering chores, and outdoor chores done in the early morning.
As I get older, the extreme heat is much harder for me to tolerate.
It has sapped my energy and interest in just about all activities.
I did enjoy, yesterday afternoon, sitting in front of a fan and watching a DVD recording of the opening day of the Tour de France, and sipping iced tea.
