Looney!

Sweat glands for thermoregulation are wonderful things.

they are indeed. I hope it was arid enough for them to have really helped.

Yeah, it really helps when I've arid everything out.

If you wet long enough, there'll be a pun forthcoming.

yeah, you never know what'll transpire...

of course, if there is something wrong with your brain, maybe it's because it got slowly cooked by bicycling in 102F.

that said, I still want a bicycle. It's getting to be time to start looking, I think.

Really, what happens is that because of the increased efficiency of the person + bicyclist combination vs. person walking, you go farther for the same burned energy.

thus, the bicyclist, in hot weather, heats up less than the ped.

and at equivalent amounts of effort, the cyclist is able to take advantage of greater airflow for greater transpiration cooling.

yes, there is that aspect. What about going up hills? I always found there was a point (of steepness) where I could no longer ride, but could still walk.

not sure about caloric impact going uphill on bike vs. foot, but the real limiting factor uphill is the point at which you can no longer balance the bike because the pace has slowed too far.

also, biking downhill is faster and requires less energy than walking downhill.

well, yes, I'd re-mount for the downhill, of course. And yes, the balance thing is interesting. Hmm, on a tricycle with very low gears, I could imagine I might have stayed with that.
