The Nature of Choice

A quantity of radioactive material has a Choice to decay or not to decay. The more time that goes by without it decaying the less Choice it has - like the more time you spend doodling instead of studying reduces the choices of colleges you can go to - and the more likely it is to decay. External 'pressure' influences Choice. The fact that you're on a diet means you will choose an apple over chocolate; this is 'pressure'. A more accurate name for this pressure is Influence (in). Time influences the Choice of Uranium to decay or not, weight influences the Choice of fruity or fatty snack. Whenever there is a Choice, there is an Influence.
in is quantifiable; for Uranium: as time increases, Choice decreases. Weight up, choice down. Doodles up, choice down. Influence is inversely proportional to Choice.
This type of Influence is, of course, weighted. If chocolate and apples were equal in fat the Choice would not become easier. If the nature of radioactive materials meant that they didn't have a half-life the Choice to decay or not would not change.
This has relevance to the QT thing, but I'm going home in 25 minutes and wanna post another pic instead. More later.
