Susan Christiana, I am becoming aware of Medium army of encouragers of which you are one. Thank you for your kind words. Since childhood I have always felt comfortable with older folks, usually kinder, gentler and wiser.
Wonder not how long it will last enjoy the day you are in.
Turn the heat around make it a friend, go indoors or a shaded area when it is too hot and relax knowing there is not much else you can do. If that fails run a bath full of cold water ( smile ).
PS I am aware I speak from a position of ignorance of heat in the US so you well may detect it.
