Married at 18, never divorced, grandma at 46, not old by any standards now that I’m 50. My loving family keeps me young, happy and content. What kills you is stress. Those common viruses that you talk about will attack when you are under extreme stress. I have seen the effects of stress and healthy eating and exercise don’t seem to make a difference.
If the hot dog I eat today means one less day in the nursing home, so be it!
I got an interesting lesson about this in high school. A typical teen student, athletic even, popular, and since he was a child, one of the last of the polio victims, his doctors told him he would be dead by 25, so to plan accordingly. He did.
He had scheduled his life around a 25 year life expectancy, eliminating a lot of what normal people do. His parents had no problem with him underage drinking, though he didn’t care for smoking. They would buy him anything he wanted, as it was his “inheritance”. He went to school to socialize with those his own age, though no pressure about grades.
All his friends and even girlfriends knew about it, and it was surprising how mature everybody was. No morbidity, no fretting, no fussing. For being able to do most anything he wanted to, he still acted normally, and actually graduated with his class.
And, his doctors were right to within a few months. He even arranged a wake for himself, so he could be honest with everyone and so that there would be no bad feelings or memories after he died.
He died in his sleep, and was buried in his letter sweater.
