Whether or not you worry or want to worry, has little to with whether or not you should or need not investigate cardiovascular health.

Clearly, my answers to most questions in these forums exceed a given forum users actual interest. I'm pretty sure you wish to remain ignorant of all the factors that contribute to cardiovascular "health" and simply want to be assured that your exercise is somehow "good for you."

Heart rate is only one aspect of cardiovascular physiology. There is nothing about this thread that proves that your current heart rate is healthy or unhealthy. However, in the absence of any other known risk factors or symptoms - one might conclude that your heart rate is normal.

And this is my point - for a "normal population" - exercising to the point of maximum heart rate IS a risk factor. And that is why I took the time to tell you to consider other factors before deciding "I'm normal."

Never mind.
