Man Does Not Live by Bread Alone
(people's psychological needs as well as their physical needs must be satisfied if they are to live)
Holy cow, Pete! Don't you think about anything but food? After all, man does not live by bread alone.
Look! Don't go around thinking that all I care about is food. I know that there's more to life than eating. After all, who but me is doing twenty hours a week of volunteer work at the community center? And who do you suppose spends his weekends as a big brother for underprivileged children?
I've never doubted your dedication to helping others. I just think your dedication to food might be somewhat exaggerated. All that extra weight you're carrying around isn't doing your heart any good.
