Calling on The Hermit

Riddle me this Batman....

I have been hearing about younger (than me) people suffering from health problems (heart, diabetes, blood pressure etc) and I think to myself:

"Self, why do you continue to (mal)nourish your body with sugar and chemicals? "

And I can't really come up with a good explanation. I am overweight (technically obese) and I "know better". I was thinking the other day that I am healthy. My BP is good, no glucose, cholesterol is good, no heart issues. My internal organs are doing well.

My back, hips and joints are another story.
