My dad has high blood pressure (& recently had a heart attack- his father died of a heart attack and his grandfather died of a heart attack -so most of the men on my dads side of the family have had heart attacks) and my mom is diabetic so they are nuts about taking my blood pressure and sugar level (my sugar was 98 today, my mom said that was good. My blood pressure was 120/78 which my dad said was good but hes worried about my pulse it was 100 and the last time I got it checked it was 104. My dad said it might have been where I talked a little while I took it, but it always says that)

So my question is why do I have such a high pulse? Im 21 years old, 5’6 at 198lbs and I’m also a smoker (1 pack a day). But my dad is 5’11 at 220lbs and he smoked for years but his was never that high.
