Is this good for my age?

I'm 15 year's old and today, my Dad took my blood pressure and it was 107/59. Is that good for me? I don't have any major health problems. When I was 3 week's, I had heart surgery for a hole in my heart, fatty tumor and my atrieres were switched. Also, I have acid reflux/gastroenteritis and it can make my chest hurt once in awhile. But, my Dad says the reason my blood pressure is like that is because I'm so calm. I can have a bad temper (which I get from my Dad but, it's just getting angry, not violence! don't worry.) and I can freak out and yell but, lately, I've been really calm. But, when I get mad at the littlest thing's, I can feel my heart pumping. But. I'm normally very calm, lately. So, having a 107/59 blood pressure for a 15 year old, is that okay? Also, I'm at normal weight, not to light or not to heavy, for a 15 year old. So, I was just wondering about it? Thank you!

There's absolutely nothing wrong with your blood pressure.

Yup. That's perfectly normal.

It's a problem if you're either below 90/50 or above 120/80

Relax. Your fine. You must be getting some exercise that's keeping your BP on the low side of normal. No, you are not too low. When I was your age I was an athelete and my BP was around 80/40. BTW: 120/80 is about average.

you sound healthy and just to let you know that little things like checking your blood pressure after a meal could show a slight rise in pressure.
the main thing is try to exercise everyday and eat good foods
a check up once a year to give your doctor some base lines of your health is always a good idea.

Average is 120/80. You're a little low, but it's nothing to worry about. If you are really concerned, talk with your doctor. Their blood pressure machines are much more accurate than at-home ones.

You juz normal. Don't worry about it and take a regular exercise for it. Release a tension and think about happy thing ok!!
