I Didn't Eat It!

Last night we had company; so during the day I was making a jello cake.  Karen came by and said, "How come you're making that?  How are you going to resist eating it."  I said "I am just NOT going to eat it."  And I didn't.  My friend who came over last night said "Be careful after we leave, and don't go and have a piece."  And I didn't. Advice well taken.  This is what I think, "How many seconds does it take to eat a dessert?"  Donaldo said 75 seconds.  So do you want to eat dessert (or something else) for just 75 seconds of pleasure and then deal with the guilt and calories later.  This theory sounds easier than it actually is.  Why is this?
