answer:You may be suffering from low testosterone. Men with low on testosterone often just don’t care about anything. They may feel like they just “exist”. Pleasure and desire can also be greatly decreased greatly affecting your career and your relationships. Perhaps you have some of these other common low testosterone symptoms: depression, mental fogginess/fuzziness, difficulty concentrating, anxiety, loss of muscle, increased weight gain, decreased facial hair and a general feeling of not caring about anything. It would be a good idea for you to talk to a medical doctor about this. Good heath to you!
