Hi jackknife-
No, you're not a fossil! Ultra Fuel is one of the many carbohydrate-rich energy drinks that is on the market. It also contains a bunch of vitamins and has a pleasing taste in my opinion. You generally see it in healthfood stores and gyms.
As far as your tires go...if you're not using really aggressive knobbies, you're already getting some of the benefits of decreased rolling resistance. Both my roadbike and my "winterized" mountainbike roll on completely slick rubber with no tread. I've never experienced any problems with thorns, glass, or anything else where knobbies would have prevented a flat. The grip on pavement is outstanding because all the rubber meets the road, similar to the rear tires that one would see on a dragster.
My offroad knobbies have poor handling characteristics on pavement because the actual "contact patch" is reduced in size. The opposite is true on dirt when each of the knobbies can really sink and "bite" into the terrain along with the rest of the tire. Happy Trails!
