My wife Kara became ill after eating some ham over the holidays. So, to prove that I'll turn just about anything into a puzzle... here goes!

By changing one letter at a time to form new words (and leaving the other three letters in their original positions), how many steps will it take you to convert the word FOOD into the word SICK? I was able to do it in five steps:

F O O D
_ _ _ _
_ _ _ _
_ _ _ _
_ _ _ _
S I C K

Here's one SOLUTION.

ONE SOLUTION:

FOOD > HOOD > HOOK > HOCK > SOCK > SICK.
