Out of the Blue

Various factors in the Gunnar-man's recent spate of peeing suggest it's psychological rather than physiological, but I am familiar enough with my own tendency to be dogmatic (no pun intended) in analyzing things when I have a preconception about what's going on that I can't rule out it being medical, so its come to the point where it's time to ask the vet if she sees any reason for this sudden flood of urine we're getting to experience.

Flood of Links:	Thanks Ant and Acleacius.

The Portal video had excellent effects, but one thing always bothers me about these Portal videos. They all do the perpetual falling thing. It always ends safely. Sure, videos are entertainment, but when set in a context of Portal physics in "real life" there has to be a nod towards physics in real life. Terminal velocity is about 120mph when a skydiver takes maximum resistance (i.e. belly down), and it's reached in about 15 seconds. Going feet-first, all tucked in to avoid losing limbs on the edge of the portal, the speed could be getting on for 200mph. True, the upward motion should slow him until he reaches 0 mph at the peak. So we'd have to consider just the subsequent falling back. Even if we're to assume the height reached is correct when the exit portal is moved to the back yard, he free-falls after that for ~5 seconds, so assuming a belly-fall shouldn't he be going around 85mph when he falls back into it, and not much less than that when he goes splat onto the ground? Though maybe he'd already be dead from the instant change in direction.
