You’re overweight.

You decide that you need to lose about 20% of your current body weight to be healthy.

On one hand, you could examine your caloric intake and energy expenditures and develop a long-term plan to decrease the former and increase the latter.

On the other hand, you could decide that this would take too long and wouldn’t be flashy enough. How about just chopping a leg off? I mean, the healing process might be a bitch and it’ll be a pain in the ass to get around, but at least your weight will look better, right?

Another parable:  An economically minded peasant conducted an experiemnt to see how little straw he needed to give his donkey.  But unfortunately he couldn’t finish the experiment, because when he got down to one handful of straw per day, the donkey dies.
