"If I'm hungry, I eat. Thus I enjoy life." Self-indulgence can be pretty short sighted. If you want something, do you always buy it? Do you ever save money?

"If I'm hungry, I eat. Thus I enjoy life." Self-indulgence can be pretty short sighted. If you want something, do you always buy it? Do you ever save money? Do you ever clean your house? Have you ever learned something that was hard/not-enjoyable because you knew eventually you'd more satisfied? Your body is convincing you that you need to eat because historically, humans were well-served over-eating when given the opportunity. Now, if you self-indulge, you'll get fat. You'll feel less healthy. You'll die earlier. Many people will look down on you. You'll leave behind a widow, children, and friends who wished you'd lived longer. You'll annoy people on planes. If you're ever single, you'll likely stay that way for longer periods of time. You'll have a harder time getting jobs. You'll eventually pay more in health insurance. And, sure-- vanity, too. It's funny that someone who's racked up ~6000 karma on a site like HN is actually positioning himself as somehow above vanity.
