It's 94 at the lake

 And the air conditioning died.

  

 We've contacted the new owners and they've decide to replace rather than repair.  That's what the new environmental laws do--force people to buy new rather than repair. It's supposed to be cooler tomorrow, and we haven't had the really hot days that Columbus has experienced.  The AC was new when we bought our cottage in 1988, and we replaced it in 2002. So I hear 20 years is a good record for AC units. Tonight we go to the picnic in the park--last week was too rainy and cold! Tonight we'll be slapping our ankles as the bugs in the grass bite!

Laptops and sperm count in men

On someone's Face Book page I saw a photo of a lecture hall where everyone had a laptop on knees or lap. I was pretty sure I'd seen something years ago about heat killing sperm or reducing sperm count. I know my laptop can create heat even through a thick pillow on my thighs, so I looked it up. Here's what was at the bottom (no pun intended) of advice on taking a laptop to college classes.

Guys: if you put the laptop on your lap, please also be aware that the increased temperature can reduce your fertility. The effect is not so strong that you can count laptop use as a contraceptive, but it’s something to think about. You might also think about the effect of elevated temperature on spontaneous mutation rate in those little gamete vehicles you have on board.
