Time and energy
The other day, I needed to get change for a purchase from another shop, so I went to Nakumatt, the only store in Kenya where change is always plentiful. The lines were so slow and so long that I went to a nearby health food store and bought an overpriced "energy bar". I was highly amused to read the wrapper later and see that it was imported from my native Denver, Colorado.
By the way, I don't recommend that particular flavor; mixing cinnamon and chocolate isn't a good idea - at least for my taste buds.
The wrapper states, "Each bar is a gentle balance of high energy and sustaining foods that leave you with a pleasing sense of vitality and well being for hours to come." That is what I felt, but I think that was from my cup of coffee.
