Hi I am 29yrs old weigh 240lbs, and 5'8 I dont have any medical condition, dont drink or smoke. However my heart rate has always been 115-125bpm as far back as I can remember, when I hear about others, mine is comparatively high, is it normal? should I be concerned, 2yrs ago i talked to one physician and he laughed it off saying nothing to worry, maybe high is your normal, does it work like that?
