You can infer that you have a high/low blood pressure and/or a high/low heart rate.
That's about it really.
low HR & low BP != good health
Yes, most healthy people DO have low numbers, but that doesn't make immune to congenital/hereditary problems like diabetes, heart disease or the various other things that would affect an otherwise healthy person.
Some people just have naturally low HR & BP. Even in my suckiest of shape, my pulse was never higher than 60 at rest. And even though I could run 5 miles in under 30 minutes, my BP was always higher than normal.
They are a guide, nothing more.
