Technological advances allow more work to be done from remote locations, so some computer programmers are able to work from home. Most programmers though, do work in clean, comfortable offices and spend most of their time in front of a computer. They usually work full 40 hour weeks and may be required to work overtime to meet deadlines or fix technical problems. Because of the amount of time spent in front of a computer terminal, programmers could be susceptible to eyestrain, back problems, or hand and wrist problems such as carpal tunnel syndrome.
