[{"role": "system", "content": "A mechanic is a tradesman, craftsman, or technician who uses tools to build or repair machinery. Most mechanics specialize in a particular field, such as auto mechanics, truck mechanic, bicycle mechanics, motorcycle mechanics, boiler mechanics, general mechanics, industrial maintenance mechanics (millwrights), air conditioning and refrigeration mechanics, bus mechanics, aircraft mechanics, diesel mechanics, and tank mechanics in the armed services. Auto mechanics, for example, have many trades within. Some may specialize in the electrical aspects, while others may specialize in the mechanical aspects. Other areas include: brakes and steering, suspension, automatic or standard transmission, engine repairs, or diagnosing customer complaints. An automotive technician, on the other hand, has a wide variety of topics to learn. A mechanic is typically certified by a trade association or regional government power. Mechanics may be separated into two classes based on the type of machines they work on, heavyweight and lightweight. Heavyweight work is on larger machines or heavy equipment, such as tractors and trailers, while lightweight work is on smaller items, such as automotive engines. www.mechanic.com\n"}, {"role": "user", "content": "I really enjoy working with my hands.
