Certainly is too hot not to have air---I'd be living (and sleeping) in the one room that does.
As for the heat, there are a lot of people our age, and older that seem to run on the cold side. That is not me. I hate the heat and the heat hates me.
Several years ago, right before daughter went off to college, we took off on the last vacation we'd take as family.
We did several things but on the way back home, we stopped a Six Flags. I overheated. It's like getting the flu and I ended up spending the day in the health care facility drinking Gatorade.
Since then, I can't take the heat and if I'm not careful, I'm down for a day or more.
As for the Hoverround, I want a red one too. Bright red with bells and whistles so everyone knows I'm around. Foghorn would really be nifty.
Although I don't want one so bad that I don't get up and exercise---going to fight as long as I can.
As for cleaning, my youngest had (kind of in remission right now) allergy related asthma. I became a fanatic about cleaning---we're talking toothbrush. In the last few years, I just don't seem to have the drive to be that detailed.
Besides, I like the lived in look.
