Re the video:
I can see gym cycling and arousal - none of the aggro with car drivers, no rain, no potholes, and you can look at the other person safely. And all that sweat (aka pheromones).

But if pumping legs gets you going, dancing would work, and looking at the opposite sex is obligatory. "Perpendicular expression of horizontal desire" as GBS put it.

Ahem! Despite the amount of dancing I do - well let us just say I need more dancing! Or a younger body.
