The work of a scientist can be very demanding. Scientists are usually under intense pressure to innovate and discover, as well as regularly publish new findings. The fierce, and at times cut-throat, competition in the industry can end up being very stressful for scientists. In addition, scientists are prone to stress especially when they discover something harmful in their research. Others spend long days at work, and still have to spend time on research. Such factors can lead to depression and suicidal tendencies.
