Because we fear leafy greens.
Lachanophobia: The fear of vegetables.
Other things you may fear:
Willowphobia: The fear of whipping one's hair back.
RT@#ophobia: The fear of twittertalk.
Bathysiderodromophobia: Fear of the subway. (Really.)

If you suffer from any of the above, we know just the man for you.
