Are the kind of person who eats the one marshmallow now or do you wait and have two later?

(Paraphrasing from Wiki) -The Stanford marshmallow experiment was a study on deferred gratification. The experiment was conducted in 1972 by psychologist Walter Mischel of Stanford University. The experiment has been repeated many times since, and the original study at Stanford has been regarded as one of the most successful behavioral experiments in predicting future success. In the study, a marshmallow was offered to each child. If the child could resist eating the marshmallow, he was promised two instead of one. The scientists analyzed how long each child resisted the temptation of eating the marshmallow, and whether or not doing so had an effect on their future success. The results provided researchers with great insight on the psychology of self control.

So, what type of person are you? Do you eat one now or wait for two? Have you done this with experiment with anyone you know?
I’m the kind of guy who tries to sign up for the study twice so I can get 4 marshmallows later.
