Cetaceans have lungs, meaning they breathe air. An individual can last without a breath from a few minutes to over two hours depending on the species. Cetacea are deliberate breathers who must be awake to inhale and exhale. When stale air, warmed from the lungs, is exhaled, it condenses as it meets colder external air. As with a terrestrial mammal breathing out on a cold day, a small cloud of 'steam' appears. This is called the 'spout' and varies across species in shape, angle and height. Species can be identified at a distance using this characteristic.
Products of fashion, by definition, have a shorter life cycle, and they thus have a much shorter time in which to reap their reward. A distinction is sometimes made between fashion items, such as clothing, and pure fads, such as the notorious pet rocks. It is not always immediately obvious into which of these two categories a product falls. When they were first introduced in the early 1980s, in-line skates seemed as if they might be a brief fad. But 25 years later they were still selling strongly, firmly set in the mature stage of their life cycle. They may not be destined for the life cycle of the corn flake, but they have already outlived many seemingly more permanent products.
Fox Shocks offer the ability to tune the quality of the ride by adjusting the compression damping of the shock for aggressive operation or heavy load compensation. The ride tuning is accomplished by rotating a knob located on the remote reservoir on each shock. These shocks also offer the benefit of being rebuildable. All shocks have a finite life based on the quality of the oil; the shear properties of the oil break down over time, losing their damping characteristics. Fox Shocks offer the ability to replace the oil and re-lube the sealing surfaces to ensure optimum performance throughout the life of the shock.
