Water Bottle Cap

Everytime I read this, I try to determine what it means. I mean, is it "Still, naturally feel good?" or maybe "Naturally, feel good still"? After maybe 5 minutes of intense ponderance, I come to a conclusion that I have no freakin' clue.

*Update!* It's been 2 weeks and we have finally figured out this bottle cap. In England, or Europe rather, there is "still" water and "sparkling" water. Sparkling is carbonated and still is not. So, the bottle cap indicates that it is ~still" water while saying, "Feel Good Naturally". Wow, it took us Oxford kids 14 days to figure that. Aren't we supposed to be intelligent or something?
