I am going to try and make a short response to your points.   I will agree that losing weight might not be easy, but that doesn't make it impossible. Changing your height (without extreme surgery) is impossible, and dyeing hair is a personal preference that you can choose to do, but you can't change that your hair thins or grays. You can change your unhealthy lifestyles (i.e. being obese) even if it takes alot of work. I am 24 and starting to go gray, no matter how hard I wish it wouldn't happen, I can't make it stop, same as you.  There is also a difference between being overweight and obese. Obesity causes health problems. American obesity is a problem not just for those that are obese, but for those paying taxes. So yes all of these wonderful people in healthcare professions, public safety professions, and public service jobs. The ones in healthcare and public safety have to risk their own health and safety for these HPs. I would re-link the post of the girl who died because firefighters couldn't lift her, but you should get my point. My mom is an RN and has injured herself trying to move some of this disgusting unwashed trash when they are in the hospital for self-inflicted beetus (SIB). Guess what, most of these POS don't have insurance or are on disability and welfare so we are paying their meal-ticket. That's right, you, me, and the rest of the responsible healthy people taking care of their own families.
