It might be "worth while" to learn the difference between affect and effect.

From my Inbox:

One suggestion I do have is to possibly get on a call with our president…He can talk about mold and its affect on allergies, and he can also provide solutions, with a VERY soft sell of our product (fact sheet attached). Let me know if that’s something worth while to pursue and I’d be happy to set it up for you (or the writer).
