I'm never going to leave the gym. I just want to be here.
Why do you want to stay in the gym forever?
I feel that I'm addicted to exercise.
Exercise is healthy, but only in moderation. Exercising obsessively can lead to injury and exhaustion, so you shouldn't manically exercise. If you feel like you have a compulsion to exercise, you should seek help from a therapist.
Nah, I'm cool, exercise makes me feel good.
You need to let your body rest as well. You can't grow muscle and get healthy if you don't give your body enough rest time.
