The correct answer is Unhealthy Lifestyle, Bad posture, Repeated movements, and Heavy lifting. These are all risk factors for RSI (Repetitive Strain Injury). An unhealthy lifestyle, such as poor diet and lack of exercise, can contribute to the development of RSI. Bad posture, such as slouching or hunching over, puts strain on the muscles and tendons, increasing the risk of RSI. Repeated movements, such as typing or using a mouse for long periods, can cause overuse injuries. Heavy lifting can also strain the muscles and tendons, leading to RSI.
