Poor health of parents can have nothing to do with genes but a poor lifestyle of those parents. Genes have some to do with how long a person lives or what they might end up suffering from, but it's not everything by a long shot, as there are countless cases of parents living longer than children and siblings living longer than other siblings. It's lifestyle by and far, starting with diet, then exercise, stress avoidance and genes. You keep saying you have superior genes and we have no evidence of this, nor do you. if you aren't 60+, you have no idea what's waiting for you when you hit that age. Some show aging signs young, and it still depends a lot on their personal lifestyle. What you pass onto your children might not be evident until they also reach their 30's or later. My parents both passed at 79 (dad, likely from smoking 3 packs a day for 60 years), and mom at 84 (never smoked, exercised, ate healthy but lived with that smoker for quite awhile), both from cancer. My brother died from a heart attack at 67, brought on by diabetes, which a few family members have, including my son, while I don't, and he always eats well, never smoked, drank to excess and exercises. My brother was told to lose weight, and he didn't listen, and his normally healthy heart and body was brought down by that diabetes and not losing the weight that diabetes feeds off. I have good health, and was buff for 50 years, until I slowed my weight training down just this last year, which will continue again. All my children exercise at least somewhat, with some all the time like I did. They all eat healthy, and all are fit and lean, mostly instilled from my cooking and watching me exercise while they grew up, and adopting both the exercise and eating habits. This doesn't mean time won't humble them, as it does everyone, as it will you. Being fat isn't "abnormal" DNA. That's just a shot towards those who are overweight, and it isn't usually about DNA but that lifestyle they chose. You don't choose your parents, but you will see yourself in them eventually, if only a little . Overweight people who avoid vaccinations just might die because of that, as comorbidities are the main reason most pass early.
