I have kids and I want to have a long life and there are certain things that are conducive to that and certain things that aren't. I've opted for the road of happiness and long life.
I've got a real sense of three-dimensional geometry. I can look at a flat piece of fabric and know that if I put a slit in it and make some fabric travel around a square then when you lift it up it will drape in a certain way and I can feel how that will happen.
