I have received luck once but was unable to figure out what it exactly did because if it added food or tech I wouldn't be able to tell since I never pay any attention to either of these as the tribe is several months old and have an abundance of both.

I've also had takes youth and never could figure out who because with a 100 plus tribesmen I don't really know who is who except for one or two that stand out.

(I keep telling myself that I will let the tribe drop down to about 50 so I can keep up with who is who then I turn around and there are babies! It seems whenever the gong grants wisdom it is almost always making a guy a master parent and you know what that means!
