The vision requirements for becoming an air traffic controller vary by country and organization, but generally, a certain level of vision acuity is necessary. In the United States, for example, the Federal Aviation Administration (FAA) requires air traffic controllers to have distant vision of 20/20 in each eye, with or without correction. If your vision strength meets this requirement, you may be eligible to become an air traffic controller. However, it's important to check the specific vision requirements of the country or organization you are interested in working for. **

It's important to listen to your body and pay attention to signs of overtraining, such as persistent fatigue, decreased performance, and increased risk of injury. If you are experiencing these symptoms, it may be a sign that you are overtraining in strength training.

Consulting with a fitness professional or coach can also help you determine if you are overtraining and create a more balanced training plan. **

The problem with the air during strength training is that it can become filled with dust, allergens, and other particles that can be harmful to breathe in. This is especially true in indoor gym environments where the air may not be well-ventilated. Breathing in these particles can irritate the respiratory system and lead to coughing, wheezing, and other respiratory issues. Additionally, poor air quality can also affect performance and recovery during strength training. **

It's also important to allow for adequate rest and recovery between workouts to allow your muscles to grow and repair. Gradually increasing the intensity and volume of your workouts will also help to build strength over time. **
