There can be any sort of an addiction, be it a chemical addiction which is external or an internal addiction like workaholism or food addiction. Workaholics are who are addicted to work. They feel pleasure and enjoy their work. There is no generally accepted medical definition of such a condition, although some forms of stress, obsessive-compulsive personality disorder and obsessive-compulsive disorder can be work related. Workaholism is not like working hard.
Workaholism has a negative connotation attached to it but it is used by people to express their devotion towards their career in positive terms. People considered being workaholics ten to lose track of time, voluntarily or involuntarily. Health symptoms can easily go undiagnosed or unrecognized. The incessant work-related activity masks anxiety, low self-esteem, and intimacy problems. Workaholics feel the urge of being busy all the time, till the time that they perform certain tasks that are not required.
Any kind of addiction chemical or non-chemical is a risk. I think there should be a balance in one’s life between work and enjoyment. Balance is necessary in life it takes time out for a person to fulfill all their duties at home, at work and takes time out for you to follow your hobbies.
