I subscribe to the "three flags" method of determining what may be of valu to me and my PD. If one source tells me something works, or would/could benefit me, thenn within a few days a totally unrelated sourcw seems to tell me something that supports the first source, I start to pay attention. If a third source verifies what I'm hearing I have learned to sit up and evaluate it for myself. The use of common sense is sometimes of valu also.

Keep your head down and your chin up....and you'll be fine.
