Purina Diet

A friend of mine has a big Labrador retriever. While I was buying a large bag of Purina at Wal-Mart for him, a woman behind me in the check out line asked if it was for a dog (duh?).
On impulse, I told her no, I was starting The Purina Diet again, although I probably shouldn't because I'd ended up in the hospital last time. I'd lost 50 pounds before I awakened in an intensive care ward with tubes coming out of most of my orifices and IVs in both arms. I told her that it was essentially a perfect diet. The way that it works is you load all your pockets with Purina nuggets and simply eat one or two every time you feel hungry. The food is nutritionally complete so I was going to try it again.
I have to mention here that practically everyone in the line was by now enthralled with my story, particularly a tall guy who was behind her.
Horrified, she asked if I ended up in the hospital last time because I'd been poisoned.
I told her no; I was sitting in the street licking my balls when a car hit me. I thought the guy behind her was going to have a cardiac, and would require need help as he laughed so hard he fell to the floor.

Stephen Smale

Born 15 Jul 1930. American mathematician who was awarded the Fields Medal in 1966 for his work in topology and dynamical systems. One of his studies (1961) was on the generalised Poincaré conjecture, a famous problem of 20th-century, which asserts that a simply connected closed 3-dimensional manifold is a 3-dimensional sphere. Smale proved a higher dimensional Poincaré conjecture for an n-dimensional manifold where n is at least 5. In other work, related to strange attractors, one of the early fractals to be studied known, he discovered strange attractors which lead to chaotic dynamical systems. (An attractor in classical mechanics is a geometrical way of describing the behaviour of a dynamical system.) His recent work has been on theoretical computer science.
