It has been my experiance that when somthing that is said to someone that that dont want to hear yeah they dont like it, but it gets there mind wondering and thinking... So they might or might not take your advice but if they do in the long run they will appriciate you for saying something to them...and eventually will come to you and tell you that...Somtime the health of other is the most imprtant aspect of life and informing someone to what you have found out can change them and help them... I dont know that is my feeling on this matter...

"Unspoking words hurts more then spoken"

that is the way I feel and always will

I really hope that helps you

good luck and may God Be With You...
