The longer I am in it, the more acclimated to the heat I am. I am not pretty about it, sweating from head to toe. If I stay indoors all day, away from the heat, I can't take it even to walk to the mailbox. I pick up mail by car more in the summer.
Long ago the climate was not as it is today. There was more land, less cement that radiates heat. Early writings described Galveston Bay as frozen over in the winter. I'm sure the summers were much cooler...in their mud huts. Lol
