Blood work: do you care about the exact numbers?

Just thinking about this today. Had my physical a few weeks ago with blood work done beforehand. The doctor told me everything looks great – sugar is fine, triglycerides, etc. He said the only thing that is borderline is my cholesterol but I could look after that with diet and exercise. I was very content with hearing all that. I know there are people who really delve into the exact numbers of every aspect. How do you feel about it? Am I being sanguine, (to make a pun) ? No right or wrong answers here; just curious.
