Always begin by checking the power steering fluid level because the steering pump is the heart of the power steering system. If the level is low, we could assume that the system is leaking fluid. Next, itâs important to check the color and viscosity of the fluid. Normal color is red or straw-colored.
In order to understand both how to keep your nails healthy and how they can act as an indicator of health problems, first you have to know that fingernails are made of layers of a protein called keratin. This protein is also found in your skin and hair [source: Mayo Clinic]. But your nails are more than just keratin.
Hair and nails are made predominantly from proteins. Depending on the type of protein used, the structures made can be soft and pliable, like hair, or be designed for sturdiness, as is the case with nails. Some conditions, such as a fungal infection, can break down these proteins.One such protein, known as keratin, can be destroyed and turned into keratin debris.eratin debris can be caused by a fungal infection known as onychomycosis. Fungi that infect the nails can destroy small amounts of keratin, resulting in the formation of keratin debris, the Merck Manual explains.
