All three situations are roughly equivalent

Sex, dessert, and cigarettes are "roughly equivalent"? Remind me not to come over to your house for dinner. ;-)

Edit to add: Wow, some people have no sense of humor. Or at least were unable to see past the humor to the actual point. That is, that it stretches the analogy too far to equate "emotionally complicated" and "fattening" with a dependency-forming drug that will then proceed to give you cancer and kill you. Bit of a negative applause light, eh?
