Here’s something to consider: if doctors have mastered their form and know everything there is to know about the human body, why do they look like crap? Respectfully, I’d rather Lebron James tell me not to eat meat than a 5’7″ overweight white guy who looks 20 years older than he is. How many years did you go to school to learn about how the human body works? Did you learn a lot? If so, why are you aging so quickly?
Just because your mom or your doctor think that’s what you need to do, doesn’t mean that’s what you have to do. Think critically and listen to your body. You only get one go at this, and medicine is completely reactive. We truly have no idea what’s going on.
