I rang mine for the third time last night...it said it granted food. Now, the food meter stayed the same, so I figured it just made the crops come up. Today when I went in, the "west wind" was blowing, and I had 665342 food, and still had 1400 coconuts to harvest. So it doesn't always happen immediately. The first time I rang it, I had villagers embracing all over the place with most multiple births! The second time, it granted "youth"...I couldn't figure that out, until I spotted a little redhead who had been 55, a master scientist and master farmer, who was 5 years old again! And her twin, who was standing by the gong, greyed immediately. Kind of sad. The one give youth has daughters older than she is!
