One man's meat is another man's poison?

[keannu]

Do you use this idiom or sayiing a lot? It seems something useful for some one could be dangerous for another person.

ex)One man's meat is another man's poison.

I sometimes simply say 'One man's meat. . . ', knowing that the other person will be familiar with the saying and finish it for himself.
