Everybody should think twice about having their own baby when there are so many needy children in the world who want a mother and a father. You don't know the parents or medical conditions there, but they are honest with you because there are so many babies, you are guaranteed a healthy one. You have a better chance adopting a healthy baby than having your own where there is more of a risk. You can see these healthy children who want a loving home and are grateful to have a home. It loses it's potential for health and starts to border on the obsessive.
Body building is no different than gymnastics, tennis, etc.
In the recent past, I myself have been disappointed with the appearance of girls becoming too muscular, too big, too defined. There's no other sport that can do all of that, but that's the difference between general body building now that I do. You can exercise almost too much in body building. There is a happy medium. No other sport today offers you the ability to permanently increase your metabolic weight by adding lean muscle tissue to improve the condition of your cardiovascular system and the strength of your body, including bone density, and that makes you feel more energized and better about yourself.
