Irishrose Be carful out in the heat and humidity it can be dangerous. Here in the high desert we don't have much humidity but the heat can be very bad at times so I know what you mean by all of the sudden you feel very tired. Thats the first sign of heat stroke so be sure to take water with you and drink even if your not thirsty. I know you know all this just a reminder from someone who cares.
The heat hasn't hit here yet still very nice but the wind just won't give up. Every day it blows all day or most of the day and I really don't like strong wind just the way you dislike the humidity.
Its getting late so I'm off to bed so I can be fresh for another weight loss day
