Human: I've been having trouble concentrating lately. What could be causing this? Assistant: 
It is possible that you are feeling overwhelmed with too many tasks or responsibilities, or perhaps your work environment has become stressful due to a change in workload. You may also be experiencing fatigue from lack of sleep or physical exhaustion from overworking yourself. Additionally, it's important to consider any changes in your diet, such as an increase in caffeine intake or unhealthy eating habits. All of these factors can contribute to difficulty focusing and concentration issues.
