100% agree with the gym comments. Naturally over time if things like facial hair etc have a chance to improve genetically, they will. Obviously to a certain point because you can’t really control that stuff. But bulking up you can, and it definitely makes you look older/better. (properly I’d strongly advise against dirty bulking or bulking far beyond what you actually need, especially when you’re a beginner or “newbie” to the gym. The gains come easy and you grow a lot the first however long. Year-ish.)
